Gen 3 electronics (yes I know they are out dated, I've haven't spent enough time to get this done lately lol), using Reprap host on Win XP. I had to start over from scratch with the firmware/software as the machine it was on went down and I couldn't recover the files. I got the firmware set all back up properly (from what I can tell). All the axis and the extruder seem to go the distance they are told to. The issue I am running into now is that during an actual print the extruder tries to extrude WAY TOO FAST, so fast it can't actually spin. If I build up the gcodes manually, and use a slower feedrate, when I ask it to go 10mm, it actually goes 10mm, so I don't think its a calibration issue. I tried turning down the max feedrates on the extruder, but then it limited that axis feedrates (I think because the gcodes send the x, y, and e codes in one line so they all use the same feedrate); all this got me was a giant ball of plastic on the printhead. Acceleration is shut off in the firmware. Do I have to make special consideration in the reprap host to allow for printing with no acceleration? I've searched around the forum some, but haven't found anything useful (Gen3 is pretty outdated now....). Anyone who is running Gen3 electronics, what 'extruder' settings did you have to use in the host? Thanks in advance for any help you can offer. https://reprap.org/forum/read.php?12,164276,164276#msg-164276 Wed, 15 Jul 2026 15:19:34 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?12,164276,173821#msg-173821 https://reprap.org/forum/read.php?12,164276,173821#msg-173821 Adam.m.Nelson RepRap Host Sat, 29 Dec 2012 18:37:47 -0500 https://reprap.org/forum/read.php?12,164276,170383#msg-170383 https://reprap.org/forum/read.php?12,164276,170383#msg-170383
I am in a very similar situation to your. I made the decision to download the bundle X2SW [reprap.org] that combines Slic3r and print

I am quite sure that the firmware must be updated / changed, but I can't identify precisely which Gen3 elec-compatible firmware will work.

Any idea ?]]> Matthieu RepRap Host Sun, 09 Dec 2012 08:41:55 -0500 https://reprap.org/forum/read.php?12,164276,165425#msg-165425 https://reprap.org/forum/read.php?12,164276,165425#msg-165425 Adam.m.Nelson RepRap Host Sat, 10 Nov 2012 20:20:31 -0500 https://reprap.org/forum/read.php?12,164276,165089#msg-165089 https://reprap.org/forum/read.php?12,164276,165089#msg-165089
I'v tried changing the comm settings in the firmware, no luck. I tried changing the buffer size, no luck.

Below is the debug output from pronterface:


the print goes from 88.880000 mm to 111.110000 mm in X
and is 22.230000 mm wide

the print goes from 88.929000 mm to 111.120000 mm in Y
and is 22.191000 mm wide

the print goes from 0.000000 mm to 10.000000 mm in Z
and is 10.000000 mm high
