For the converters - with HPGL/PLT it's something like converting "PU Xxxx Yyyy" to "G0 Xxxx Yyyyy" or "PD Xxxx Yyyy" to "G1 Xxxx Yyyy Eeee Ffff" where the E-value is the mm-length of the line multiplied with the pulse-multiplicator.

So e.g. a line from 0,0 to 100,0 without pulse-multiplicator will result in a G-code something like "G0 X0 Y0; G1 X100 Y0 E100 F3000" with a "Pulse" every mm.

If you want to pulse the laser every 0.1mm, then you'll calculate the line-length with x10, so the E-value will change to E1000 in this code-sequence.

If you can reprogram the sender program accordingly or better create an import-converter, is depending on your programming skills and/or available sources and documentation ...]]> VDX Firmware - experimental, borrowed, and future Wed, 25 Oct 2023 11:15:45 -0400 https://reprap.org/forum/read.php?147,893672,893674#msg-893674 Re: G Code Sender for Ramps 1.4 https://reprap.org/forum/read.php?147,893672,893674#msg-893674 mrtcnblgc Firmware - experimental, borrowed, and future Wed, 25 Oct 2023 10:38:00 -0400 https://reprap.org/forum/read.php?147,893672,893673#msg-893673 Re: G Code Sender for Ramps 1.4 https://reprap.org/forum/read.php?147,893672,893673#msg-893673 VDX Firmware - experimental, borrowed, and future Wed, 25 Oct 2023 07:49:09 -0400 https://reprap.org/forum/read.php?147,893672,893672#msg-893672 G Code Sender for Ramps 1.4 https://reprap.org/forum/read.php?147,893672,893672#msg-893672 mrtcnblgc Firmware - experimental, borrowed, and future Wed, 25 Oct 2023 06:10:31 -0400 https://reprap.org/forum/read.php?147,642765,892473#msg-892473 Re: Marlin with DC Motor for Extruder https://reprap.org/forum/read.php?147,642765,892473#msg-892473

Also STM32F4 port from gloomyandy/RepRapFirmware would most likely without any changes port to STM32F1 used in Creality 4.2.2 board. Arguably most mass produced board ever. Most of Creality printers ship with it.

[attachment 117950 2.png]





The problem appeared after changing the firmware to RRF. The first 3D printer was on the BTT SKR 1.0 controller with servo motors, the second 3D printer on the AZSMZ mini controller with stepper motors (DRV8825) and the last one on the Smoothieboard controller. In all three variants, the problem looks about the same as in the photo.
I am definitely sure that this is not a skipped steps or some other mechanical problem.
Tried:
Change of acceleration towards their significant decrease
Changing driver timings
Change of motor currents
USB Printing from a Computer
Firmware RRF 3.2_1 - 3.2.2_2
None of the above solved the problem.

When rolling back to the original firmware, the problem does not appear.
When replacing the controller with the original Duet 3D (with the same config) - the problem does not appear
