I have an Elite Woodworker with Masso controller. I recently installed my new 4th axis rotary and have come across a problem.
Before starting the rotary cut, I used a level to ensure that my rectangular stock was parallel to the wasteboard, and then set the A-Axis 0. After the cut, when the machine returned to the work origin, I could see quite clearly that the stock was no longer parallel to the wasteboard, even though the A-Axis read 0 degrees.
By using a level, I was able to determine roughly how off the 0 was. On one cut, it was off by around 6 degrees, on another it was off by about 2.5 degrees. I’ve only done four cuts so far using the rotary, but I’ve had to re-level the stock and reset the A-Axis 0 each time before making any additional cuts to the same stock.
I wrote to Onefinity tech support about this, and was advised to contact Masso. So I contacted Masso, and was advised to contact Onefinity. It seems that neither Onefinity nor Masso are willing or able to help me with this.
I’m hoping that someone might have some idea about what’s happening, and How I can correct this issue. Any help would be greatly appreciated!
When I setup my rotary, I verified using a Vbit in the spindle and a V bit in the headstock chuck and tailstock center. After some shimming I was able to get parallel in all directions. (level was not a thing just alignment with the machine and rotarty)
But I think your issue is what another member posted. He found that the step count was off and for a perfect 360 rotation he had to adjust the settings in motor control.
Hi David,
Support is more than willing to work with you! They responded to your latest ticket! They wanted to ensure it wasn’t something within Masso software/firmware first.
It looks like they suggest a loose coupler on your motor shaft connecting the chuck.
Yes, they have been VERY responsive. I apologize for saying that Onefinity was unwilling to help. Onefinity has ALWAYS been responsive when I’ve had issues with my CNC equipment. I’m just a bit frustrated at the moment, because I am excited to get going with some rotary projects, and this A Axis issue is standing in my way.
From what I can tell at this point, the issue is either that there is either a loose coupler on the motor shaft or that there is some error in the step count.
I just need some guidance in how to check for both of these potential causes.
