I would set everything to default. At least "Input" to 0 and "Enabled" to N.

Do you have scale feedback? Like the following in addition to motor feedback?

If not, you should not be modifying anything in the scale menu. If so, get everything working without the scales first.

Try CNC12 v5.10.
Fix #56 in the release notes may resolve resend errors.
Don't forget to plug the Ethernet cable back in after the photo.

Your AcornSix should be sent back for update. There were 3 updates to the ACORN_6 FPGA and 2 to the MPU12b FPGA since your unit shipped. There is one update that may be relevant to your issue. The issue that may be corrected with firmware is lost position counts on drives with low maximum input rate...

If you post a report we can look into it.
Your vintage of AcornSix may need a firmware update to resolve issues with drives that have a low pulse input rate.
Did you use 5V step and direction and the same step rate for ACORN and AcornSix tests?

EtherCAT spindle VFD control is not currently supported, but will be at some point.

If you still get "MPU requested resend" in your msg_log.txt, the issue is not resolved. Try setting the network to "100 Mbps Half Duplex" as per TB270 page 5. https://www.centroidcnc.com/dealersupport/tech_bulletins/uploads/270.pdf Page 9 explains 2 ways to view the message log. ...

Set parameter 968 to 16.
The width of the step pulse is constant at a given p968 setting, so the step rate has to be set low enough for the drive. Otherwise, the short step pulse may be missed by the drive.

I would ground everything related to the dust collection unit with heavy wire going to a single point ground bar. Some dust collection units are impressive static electricity generators.

DMM is making some changes for HICKORY compatibility.
Currently available drives are not compatible.
