Pronterface will not let me change the extrusion amount (no replies)

Hi,

I'm trying to calibrate my E-Steps and for some reason pronterface won't let me change the extrusion amount. I was manually extruding the preset 5mm in some calibration runs, then left for half an hour, and when I came back it wanted to extrude 1000mm instead of 5mm. This gives an override error saying that 1000mm is too much to extrude. The problem is that pronterface won't let me change this to any other length. When I go to enter in the filament length it won't let me type anything and commands like G1 E5 or M101 E5 don't yield a response.

Does anyone know how to fix this problem? Is there any other G or M code I could try entering to manually control the amount extruded? Any and all tips/suggestions would be much appreciated.

Thanks,
Bryan

No negative z-axis using console (2 replies)

I recently finished building a Folgertech Kossel Delta 3D printer (http://folgertech.com/products/folger-tech-kossel-2020-full-3d-printer-kit), and am on to the setup phase. Following the instructions, I used the pronterface console command: G1 X50 F4000. This was supposed to lower the extruder nozzle to where it thought 50 mm above the bed is. The nozzle being far too high, I tried to steadily lower the X value in the command until the extruder was just touching the bed, as per the instructions (negative values were supposedly ok). However, I ran into a problem: the nozzle would not descend past where pronterface thought that X0 was, even with a negative X value. This is a massive hindrance to configuration. Does anybody know how to make the nozzle X value negative? Thanks!

TL:DR:
The console command G1 XA F4000 will not lower past A=0. Does anyone know how to make A a negative number?

G-code Handshake Between Host Software and Marlin? (1 reply)

Hi, I am a 3D printer enthusiast and a novice programmer. I am writing my own 3D printer host software in Python. I am able to send individual lines of G-code to my home-built printer (Marlin firmware), and now I want to try some test prints with many hundreds of lines of G-code. My slicing program saves it's G-code into a text file, and the program grabs a line and sends it serially to the printer.

My question: For sending multiple lines in order, and getting the timing right, there must be some sort of confirmation from Marlin to the host software that the previous command was completed, right? My Python host software would just send line-by-line everything in my text document as quickly as possible if there isn't some sort of handshake put into place. Can someone please help me understand how Printrun/Pronterface deals with this?

Thank you!

Hello,

when I open a .stl file it first gets converted to a gcode file.
Unfortunately, this file contains M101/M103 commands (which my reprap doesn't understand) for controlling the extruder.
Is it possible to tell the converter to use the E Parameter instead?

Linux Mint and Pronterface (4 replies)

So in an effort to cut the tether to my primary laptop and still be able to run my delta printer I took an old netbook i have (Asus Eee 1015pe N450 atom 1gig ram) and flashed it with Linux Mint 17.2 to boost the performance over win7 starter. that all worked out well. i have pronterface installed and got it to connect to the printer. it will send g-code just fine and no issues with homing or bed probing.

My issue is after hitting the Print button...no 3 seconds later pronterface is killed/shut down and my machine stops.

I have the power management settings set so it will not shut down the PC. I disabled the screen saver function. I have no other programs running other then pronterface. I am using Slic3r on my primary laptop to generate the g-code so all the netbook is doing is running the printer.

why would it keep killing the process like that?

forgive my questions as I am a compleye newb when it comes to linux. I have never used it before. I am not trying to learn it per say just trying to get a basic printer controller setup. i thnk win7 might have been too big of a resource hog.

I posted this on google delta group but this may be a better place:
I have a kossel with Marlin firmware that has been working with an older version of Pronterface and Slic3r. I am interested in upgrading to newer PF and S3 software but am experiencing problems with my Windows XP 32 bit machine. I am trying the 2014.08.01 version of Pronterface and the 1.2.9 32-bit version of Slic3r. When I load g-code generated with this Slic3R I get the following in the console:

File "printrun\gl\panel.pyc", line 231, in OnDraw
File "printrun\gcview.pyc", line 154, in draw_objects

. . . more similar

Any thoughts

Launching terminal commands from pronterface (no replies)

I'm using marlin and RAMPS and would like the arduino to send a command to Pronterface so that Pronterface can launch something in the command line (I'm using Mac OSX). I can figure out how to send serial commands to pronterface, but I'm not sure how I should edit pronterface code to make it send commands to the command line.

If anyone has any idea, please chime in! An alternative would be to have the arduino launch the command lines directly instead of going through pronterface, but I'm not sure if that is possible.

This is a 4mm open box calibration test. For some reason when loading the file in pronterface this is the result I get (attachment). I've tried different settings all with the same result.
Any ideas as to what might be going on?

Pronterface will not accept extruder input (no replies)

Hi,
I'm in the process of calibrating my new Prusia I3 rework and I have experienced a problem in Pronterface. All features appear to work properly except when I try to input data into the "Length" and "Speed" fields to advance filament, neither field will accept input. I am running on a Windows 10 platform with Printrun version 2014.08.01. Attached is a screenshot which illustrates the fields in question. If anyone can assist me in understanding what may be causing this problem, I would be most grateful.

Thanks in advance

Does anyone know how to set up Pronterface to have a specific interface/arrangement on startup?

I have been able to set up the custom buttons/macros on my computer but whenever I restart the program the window sizing changes to make the graph section really small so I can't see all of my buttons.

Does anyone know of a way to preset the window sizes on startup?

Printrun Error:No Checksum with line number, Last Line: (no replies)

I am consistently getting an error at the end of my prints which kills the print. The log for the error looks like this:

Quote
Resend: 74166
Error:No Checksum with line number, Last Line: 74165
[ERROR] Error:No Checksum with line number, Last Line: 74165

Resend: 74166

and so on, ad infinitum.....

The problem consistently happens with 6 lines of G1 commands left to run, and the printer head hangs up on the (*almost* complete) model at temperature, creating a wart on my print which ruins the print.

Here is an image showing the error, and three examples of g-code showing where the print failed:
https://www.dropbox.com/s/vanv743fyjxip9s/Checksum%20error%20Screen%20Shot.png?dl=0

This is a new problem, and the only thing that I can figure that I did to change things was to add the "Eject" command at the end of the g-code, but I don't see how that could cause this....

Any speculation on what might be causing this?

Installed pronterface but still errors (2 replies)

Hi, sorry if this question is basic but it's really giving me fits.

I installed Pronterface and spent a couple days getting errors cleaned up. I initially posted for help on the wrong forum category.

At first I didn't have numpy installed but I worked through that. One error after another I got solved but I'm stuck with the following when starting pronterface.py (by the way, the program appears to start just fine, I just have this message in the command prompt):

WARNING:root:Memory-efficient GCoder implementation unavailable: No module named gcoder_line
WARNING:root:psutil unavailable, could not import power utils:No module named psutil

I followed the steps in the readme (https://github.com/kliment/Printrun#cython-based-g-code-parser) and installed Cython and then tried running "python setup.py build_ext --inplace." When I do this, I get the following error:

WARNING:root:Memory-efficient GCoder implementation unavailable: No module named gcoder_line
running build_ext
building 'printrun.gcoder_line' extension
error: Unable to find vcvarsall.bat

I installed Microsoft Visual C++ Compiler for Python 2.7 to try and resolve the missing vcvarsall.bat

I'm using Python 2.7 and Windows 10

So here is where I'm stuck. I'm very new to this but I'm mostly finished with my first 3D printer and am trying to sort the software out. Is it worth working through this to use printrun or would another program be better?

Thanks for any help!

Hello, this is to announce SqPronterface, a port/mashup of MacPronterface using Squeak (http://[squeak.org]).

The reason of this port is because MacPronterface have some UI bugs in the last macOS upgrades but the program appears to be lost the developer in mac, also I have some old PowerPC macs: an iBook G4 and a mac mini that I want to use instead of my MacBook Pro to control the printer so this version can work with Intel or PPC macs.

I tried to implement most of the features of MacPronterface such as graphics, macros, settings, etc..., but this version don't have SD support or calling slice programs.

You can download the program or the Mercurial repository with all the files needed in:
[sourceforge.net]

Enjoy!

Hi.

I usually print from SD card but both card and card slots are getting a hammering from all the swapping.

Within Pronterface I can read the contents of the SD card but cannot write to it - nothing happens.

Has anyone got any tips on this? (Its not write protected before you ask)

Is there an alternative way to read/ write to SD Card over USB?

Setup is ramps/ marlin/ full graphic LCD

Thanks

I have downloaded the latest Printrun source onto my development machine and I have got it up and running. Now I want to be able to transfer Printrun onto my printing machine but I don't want to have to install python and all of the dependencies as it is a very low end machine. So what I'm wondering is how I would compile down Printrun into binaries. I know that I can download the precompiled binaries but they are a few years out of date and are missing some of the features that I need in the newer version.
Thanks,

Hi all,

Just installed pronterface using the latest versions and keep getting errors. I deleted and reinstalled it several times with no changes. I know the printer itself is fine because it was working before at the guys house who rebuild it. I was using an Azteeg X1 but when that died the original builder installed a smoothie board and was using pronterface. It was printing fine when it left his place.

The errors I keep getting are:
Printer is now online.
[ERROR] Traceback (most recent call last):
File "printrun\printcore.pyc", line 241, in _readline
File "printrun\pronterface.pyc", line 1713, in recvcb
File "printrun\pronterface.pyc", line 1669, in update_pos
ValueError: could not convert string to float:

Board: smoothie
Pronterface version: printrun 2014.08.01

I am able to turn on and off the extruder but that is it...

another note: when I look at the files in the printrun folder, I donot see any that end in .pyc, mine all end in .py (example printcore.py, instead of printcore.pyc)
I am not ever sure where to begin looking... any help is greatly appreciated.

Pronterface G29 report upside down - NOT PRONTERFACE (no replies)

March 13, 2017, 10:34 am

My bad. On further checking, Marlin is generating the matrix, and Pronterface is just reporting what Marlin is sending it. The problem is in Marlin. Discovered by enabling "#define DEBUG_LEVELING_FEATURE" in Marling Configuration.h, and then issuing "M111 S32" from Pronterface and then running G29. A detailed report to Pronterface shows Marlin is the culprit.

Like my tag says: Often in error, but rarely in doubt.



ORIGINAL POST:

I am using Pronterface Printrun 2014.08.01 to operate a MendelMax running Marlin 1.1.0-RCBugFix on a Rambo. I use G29 before each print to auto bed level bilinearly. I told Marlin to use 12 points. It samples as follows:
10 11 12
9 8 7
4 5 6
3 2 1
where 1 is the lower right corner of the bed and 10 is the upper left of the bed.

When the samples are completed, Pronterface shows a matrix in its sidebar that orders the data correctly from left to right, but upside down top to bottom.
The data is displayed as:
3 2 1
4 5 6
9 8 7
10 11 12

Has anyone else noticed this? I am hoping my son-in-law ( an uber-coder ) can fix the Pronterface Python file so it generates the measurement data in the correct order.
I have every reason to believe that Marlin is applying the data correctly to compensate for bed leveling, and the error is in how Pronterface displays it.
