I scoped step outs with servo not powered, noted waveform at 60 hz with hi freq riding it for 3 ms. not a sine wave. Tried MPG and found it working! Powered servo and MPG continued to work! I inverted step in wizard and 60 hz wave was gone. Ran peg-a program to completion. Problem isn't gone but muc...

All AC is star grounded. When scoping the y axis step output noted that when wires were moved the y would move slightly. Reterminated all step direction and enable signals. While wiggling wires again the same thing happened and once the y axis started running, had to power down acorn to stop it. I a...

The vfd was powered with the spindle off. I'm thinking something has been going south for a while, I am using a wallwart 5volt supply, a good one, regulated. After checking that and the 24v supply, I'll scope supplies and step and dir outputs with and without vfd, spindle on and off. This is so disc...

test.icn peg-a.icn report_985DAD489356-1005170154_2018-06-06_11-44-25.zip I created a test intercon program to just move the z axis up and down 1 inch several times, this program ran fine and maintained z axis position. Encouraged I wrote another program this one to create 12 .510 holes 1 inch apar...

report_985DAD489356-1005170154_2018-06-05_15-18-55.zip It stopped working on power up. I have not tried batteries, but I installed new duracells initially about a week ago. I've reinstalled 4.12. The MPG receives but doesn't transmit, or Windows isn't receiving. I will go over Windows settings toda...

I got the MPG running and it was great, for a while, then it stopped working.
The MPG is getting updates on DRO position from Acorn, but no commands are
received by the Acorn. The MPG shows the transmit symbol whenever any button on it is pressed.
Could the transmitter in the MPG be bad?

I am having a similar problem. Just getting machine going. DMM DM4 servos. Ran one intercon program 12 circular pockets 1/2 inch deep 1 inch apart moving only the Y axis. This ran okay. However, I cannot get a repeat of this. Z axis goes deeper on each hole, looks as if z is going faster down than u...

Does anyone have info on Sequential encoders?
I have a 25 GN, but have no docs on it.
There are 8 colored wires coming out of it, I have no clue as to their assignment.
Thank you
