One option is MPGs, you could install two MPG encoders.

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
File Attachment:

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.

Hybrid Manual/Stepper Control

Category: General LinuxCNC Questions

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?

Changes in configuration files generated in pncconfig for 7i76 to 7i78

Category: PnCConf Wizard

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.

Category: Show Your Stuff

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.

Homing open loop steppers on encoder index pulse

Category: Basic Configuration

The easiest solution for Mesa hardware is to use firmware that
includes stepgen index, then the stepgen hardware mimics encoder
behaviour at index detection.
