Dear meister:

My English isn't very good, so I don't know how to say thank you. Please forgive me.

Network card recommendation.

Super cheap and works perfectly. Just for info.
it was plug and play with intel driver.

Final update after a nights sleep it took only few minutes to fix I removed the negative values in the ini file and tested travel direction to correct it I then swapped a couple of motor connections the retested and directions where good then uncommented limit switches in INI and all working great all in took less than 10 minutes...I went down the wrong rabbit hole yesterday...thanks for your help.

The spindle motor is not implemented into the machine configuration, yet. All the legacy contactors and time-relais for controling it will be decommissioned soon and the Danfoss VFD will fully control the spindle motor. We did however already pull a shielded motor power cable which is necessary for VFD driven motors. While pulling the cable through the cable sleeve, we found another broken cable that seemed to have been damaged a long time ago – it was the cable for the spindle motor brake. The brake still works, so everything good there. For the spindle brake a new cable was added and thats where the retrofit stopped like ~2 weeks ago.

We plan to reuse the original three-phase induction motor and gearbox, paired with a VFD. This setup allows us to seamlessly adjust the speed from 0 to approximately 4000 RPM while retaining the torque advantages of the gearbox. We intend to use your LinuxCNC component to control the gearbox. However, the logic for calculating the optimal gear, executing the shift, starting the spindle, and handling all subsequent speed adjustments (must be managed by the VFD) has to be programmed. With this approach, I am very confident that the Maho will be capable of rigid tapping for large threads.

As soon as i visit my parents again, i will further work on the Maho. I hope i will get the homing working soon - pretty new to LinuxCNC HAL and slowly getting used to it.

many thanks again

fixed in main/dev

I recently made a modification that only copies the modifier files to the Gateware directory when necessary,
but I didn’t realise at the time that some of the filenames are slightly different (debounce -> debouncer.v / pwm -> pwmmod.v)

Thanks guys, got it working and after playing with parameters it feels quite workable.
The joystick is one of the ones with a button so may look at using it for fast/slow jog

Will post full file once finished

It is interesting to see your mod. It looks like you have kept the original spindle motor and gearbox control. Did you use the gearbox Comp my mate created for the 400E, or did you roll your own?

Thanks for the feedback I will try again .

When I bought the machine it would not boot, with a bios battery error message, so the original computer is probably dead, but not really a big loss... But the machine was working fine the last time it was used, a couple of years ago, according to the seller, so the original Indramat drives and motors are probably fine. Main problem is they require 380v, 3-phase and 17kW of it... A bit more than I have available in my garage. So the plan is to reduce the power somewhat (especially for the 10kW spindle motor), given the machine is only going to be used for hobby projects, and get it to run at 230v 3 phase.

With regards to ethercat vs mesa it looks to me, based mostly on forums posts, that the mesa route is safer, more tested and less potential problems, does that sound about right?

Yes
The ini file is from gmoccapy sim sample
Only adjusted machine size and speeds according to real cnc.

Dear meister:

 


When I add debounce for bitin7, the builder had a error.
Thank you

Dear meister:

I tested again, Thank you very muchimage missing /media/kunena/emoticons/laughing.png

In your ini file your max limits are negative, I doubt that is correct. Remove the - from max limits. If the motors run the wrong direction, fix by adding - to scale value as tommylight has pointed out.

Now that sounds pretty neat! I take it your Arduino Q contains literally both the mini-pc running Debian 13 AND the motion controller grblHAL STM32. The entire system on one compact little Arduino board the size of Arduino UNO!
I bought one of those Arduino Q when they introduced them. I'd love to unpack it and try that, but I'm currently working overtime on another big project, that should be done in a few more weeks...
