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

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.

Yes that's really confusing, the cable from the motor has 8 wires, I suspected that it might be a stepper,but isn't it. Yes, that's the only way I can move the axes, in ``jog'' mode.

the link i found

additional driver images

Cool. Thinking about it more, I'm wondering if I should just get a basic generic parallel port card, since I probably don't need fancy FPGA stuff for an MPG and some override switches. I guess I'm just remembering how much better my little cnc conversion runs on the mesa vs the parport. It seems with ethercat, most of that becomes irrelevant.

doing some test I got this question. what is wrong with this script ?

Do hit the right way to get the 5 axis cnc configure ?
can someone help me with it?

thanks!!
