Re: Vectric Post Processor for Acorn

I'm not at my pc right now, but when I try to export gcode with multiple tools I get an error saying the PP does not support toolchanges, and to use a different PP. that is with the centroid mm PP

I should create a new post for the problem rather than jump on this one

Re: Vectric Post Processor for Acorn

is it possible to edit the Centroid PP to allow multiple tools in one code \ toolchanges? I cannot for the life of me work out what allows multiple toolchanges in the Vectric PP

Re: Acorn + Clearpath success stories?

I've just bought 4 SDSK-3421S-RLN Servos to run with an Acorn on my AVID Pro 6060 CNC router, I've set them up on the bench and run with no issues, machine will be here shortly to tune and install

Can confirm I put in a #104 (0.1uF) and have no movement at all on the Frequency

Re: VFD Voltage/RPM fluctuating

Ok, so first move was to replace cable with shielded, grounded cable. This improved the issue but did not fix it completely. Best results were when shielding was grounded at both ends. I then put a 0.1uF capacitor across the analog outputs on the Acorn end, which fixed the problem completely. Steady...

Re: VFD Voltage/RPM fluctuating

Thanks a lot guys, I will replace the unshielded 4 conductor cable with two separate shielded, earthed cables The only controller I've built prior to his was a Gecko G540 and Mesa 5i25, fairly different setups but apparently quite robust against EMI Loving the Acorn so far though, simple to setup an...

Re: VFD Voltage/RPM fluctuating

Ok thats good info, thank you Can you clarify your wording around the grounding and twisted pair cable? I have some shielded cable, which has two separately shielded cables (image attached) Do I ground both ends of the shielding, or just one end, using twisted pair cable? Appreciate the help, Stu
