The stepgens on the 7I95 expansion connector are hardware stepgens.
I think when you said "parallel" tommylight assumed you meant a
separate parallel port.

Here's a configuration for the 7I95 with 9 total stepgens, 6 on the 7I95 and 3
on the expansion port, pinned out for the common Sainsmart 5 Axis BOB.
I dropped the sserial ports to get it to fit:

 

Chris, I guess you have already heard of viaconstructor (github.com/multigcs/viaconstructor).
If not you may can get some inspiration of the graphical part ... and it is also using Qt

Thanks for your reply. This means stepgens using parallel connector on the 7i95 in BoB are software stepgens? I thought 7i95 produces them in real time.

Rising up STEPGEN_MAX_ACC significantly, gave me much much better response, now I'm well below 0.01mm f-error during g-code run! 

 

I'm fighting with the setup of my HB04.
Simply copying over the files and adding the HAL and HALUI lines in the ini file didn't work.
Adding the loadusr line to the ini did help.
Then i ran into the error that pin "halui.spindle-override.counts" didn't exist (running 2.9.4) changed it to "halui.spindle.0-override.counts" but that gives me the same error.
#-ing out all the ofending lines till i got LinuxCNC to run worked, then in the terminal checked the pin's with "halcmd show pin" and fond that it has a different name. "halui.spindle.0.override.counts"

I now see the display matches, and updates to what the screen coordinates show. However, the jog wheel doesn't move the spindle/coordinates.
Any tips?

So is there an actual working image for linuxcnc on raspberry pi5 ? I am some what new to this but have been reading all the documents and post on here. Trying all the downloads and installing this and that to my files to have it not work quite right in the end results. Mainly issues with missing files like no network, no network manager even most the images just doing an suno update comes back missing items ? My latest was the 2.9.4 so does anyone have something at least close to boot up ready that I can connect to a mesa 7i96s ?

Any help would be appreciated, just about done with this raspberry pi idea




 

Quoted this so it does not disappear.

Why was " doobiedo " account disabled???
Not the first time....

Yes it can, although those will be software steppgens, meaning limited step rate that hugely depends on what latency the PC can maintain, usually you can get 10000 to 50000 steps per second.
If that is enough for what you need, then you can get 6 stepgens from a single parallel port, and 5 inputs.

I am ready to give up encoders. However, i am curious if parallel port can also be used for extra step gens?

thank you very much for the answer, but I really don't understand how to check it, I only know in the case when drivers , old amps` are appeared with an analog input +-10v. Yes ,that this is probably a signal ribbon cable from controller board to driver.

Please share the error report.

that's right, on my market you can find a cheap servo set from 1 kw motor + driver for 200 euros., I have to check first if it has backlash , I mean ballscrews

that I know that the drivers are not expensive, or in that case I would have to install other motors, because there is no driver for such motors with an unknown type and with 8 wires.
