Another week has gone by and I had one set of email exchanges with Omni. They finally sent me a video showing the machine operating (with my name on the machine). However, during the homing process, I noticed that it looked and sounded like the machine hit a hard mechanical stop before triggering the limit switch. When I mentioned this in a reply, I got this response:
"Dear Zach, Thank you for reply, this is the difference between stepper motor and servo motor, if we use servo motor, this matter never happen."
This response doesn't jive with my experience. I have built several machines that use Mach3 with both steppers and servo drives and I've never hit the hard stops when the limit switches were configured properly. The limit switches always trigger first and stop any motion. It is my understanding that as far as Mach3 is concerned, it is just sending step and direction pulses to the motor drives, regardless if they are stepper or servo, and waiting for the homing sensor to trigger. Does Omni's response make sense to anyone else?
I asked them to please correct this issue and send me a new video, but it's been three days and no response. I am getting a bit nervous and impatient as the initial quote said the router would ship within 15 days and we are now well over two months.
Oh, and for those that care, here's a link to the video they sent. There is a lot of factory noise in the background, so you might want to turn down your volume...
