On the Proma, the first and second settings should be set at minimum, i do not recall what was the third and forth settings.
Only after having this work you can set voltage higher if it wobbles a lot while cutting.

Thanks for the answer, but I understand that I have to edit it.
Only the 7i76 card has a different pin arrangement. Otherwise, the pins on P1 are DB25. Fortunately, the pins for the first four axes are identical. I already wrote that, it works without problems.
But while the 7i78 has spindle control, serial interface and encoder for the spindle on pins 05-13, the 7i76 has an output for the fifth stepper motor, two serial interfaces and an encoder on the same pins. That encoder is labeled ENx, unlike the encoder on the 7i78 - it is QUADx. I don't know if it's the same.
So if, for example, I activate the spindle encoder on P1 in pncconf, will it be the same for the 7i78? And further, on connectors P1 and P2 (on which the 7i78 can be physically located), there is no option to set spindle dir, enable. I set this on P7 but I need it to be on P1. Will it be enough to overwrite the IO number and will it work?
Let me not forget, on the P7 pins it is possible to set the direction of rotation for the spindle - two pins, but on the P1 DB25 there is a SPINDIR pin which is one pin. So if I set one pin on P7 to CW and the other to CCW, will it get to the right place on the 7i78?

Voltage is set to 100 and H-t to 5.

What settings are on the Proma THC150 ?

Hi All,

I am using 7c81 board, raspi 5 with thc proma 150. I am using QTplasmaC 
The gpios and leds for UP, DOWN, Arc OK are getting connected and blinking.
However, the Auto Z axis movement not happening with thc proma 150. Attaching the files for your reference. Please help.

That is a very good idea as it eliminates many issues caused by other methods regarding feedback and jumping to position and ...
There is another similar topic going on here on the forum but i do not think this idea was presented there, i will double check if i bump into it.

Use simple text editors included with Linux, like Xed for Mate, Kate for KDE, Mousepad for XFCE, Gedit for Gnome, etc, etc.
Or install (might be already for LinuxCNC ISO) Geany as it has more features and can do highlighting and stuff.
A correction, the Mesa 7i73 is a SSerial (Smart Serial) card, not serial as serial is usually referred to RS232.
You can also edit the existing config with the PncConf wizard, it has the option to edit at the very start. Beware that any manual editing of the config files will be overridden if you edit them with the wizard.
Also, you can make as many configs as you like for the same machine or for other machines on the same PC, so feel free to experiment and edit as much as you like or need, but do make a habit of saving backups of working configs.

A new day, new challenges
I'm trying to configure MPG, added HAL pins, seems like everything worked out. But there is a problem I can't solve. When MPG is activated, it is still possible to change the increments of movement on the screen. It would be great if this widget could only display the selected increment without the ability to change it. And when MPG is inactive, it should be possible to change the value on the screen again. But I couldn't figure out how to do it.

parent.status.file will return the loaded file path.

Hi Folks,

I have a bit of an odd use case. I have an RF45 clone machine, and given the position of my z crank, I don't ever want to touch it, and would prefer to use the Z controls of LinuxCNC. However, I want to maintain manual control of my X and Y crank for the occasional manual operation.

Is there a reasonable way to make LinuxCNC control my Z, without getting unhappy about following errors on my X and Y, without having some kind of "modal" behaviour, where it "snaps back" to the commanded position when I exit that mode?

Hello. I would like to advise how to change the configuration files (I assume it concerns .hal and .ini) generated by the pncconfig program for 7i76. Linuxcnc is installed on 7c81 and the firmware is for two 7i78. Two axes for the lathe and most of the necessary switches are without problems. However, I need control of the main spindle and input from the incremental encoder for the spindle and a serial port for the 7i73 handwheel and possibly additional buttons.
I apologize for the possibly trivial question. But I had a break from using Linuxcnc for several years and I simply forgot a lot of things, not to mention that many things were never completely clear to me.Now that I'm retired, I finally have enough time for all of this, but unfortunately, it's too complex for me.

if you don't want the 'axis' gui at all you can set DISPLAY entry in the [DISPLAY] section of your ini from 'DISPLAY = axis' to 'DISPLAY = halui'

Note:
if present you would also need to comment out 'HALUI = halui' in the [HAL] section

i just order some shift level converter can use whit rpi gpio can make out 3,3V to 5V all gpio pin, and then one optocoupler board can add rpi inputs safe, 5V in to 3,3V to rpi,
then can add all STEP,DIR,Enable pins traight to drivers DM556 i used normal,
but problem is were have image can use rpi3, not need be fast, this come only dovetail jig tool make long plank top dovetails not more, no need be full cnc, working area has need only XY axis, what has moved Z axis to 90 degree and spindle have horicontal not normal vertical system. simple hardware but image need old rpi3 board first.

forum has made help any peoples how do linuxcnc to raspberry etc other linuxcnc problems, forum need help and teach all newbie how make somethink. my own language not have forum and maybe not many peoples who can help newbie user, Finnish language need be. but i believe not have many peoples. i has build many many cnc machine before but now think need one small simple dovetail tool made whit my old rpi3 board but search google lot and not have any image what can use, all has only lot problem code and install and what have kernel compile or what need doing not understand and know what need doing. need only image what can install to SD card simple not more need doing. same than normal computer can install linuxcnc 2,8,4 my daily used cnc machine, easy simple fast install and setting workig. no problems, why not has made normal image to SD card and can use similar than computer this working. not big job all computer engineer gurus and nerds. all not have nerd and understand linux code but lot have peoples who want use rpi3 cnc.
