I’ve noticed that homing is not perfectly accurate. I can home, zero the machine work coordinates, cut, then re-home, and cut the same thing and it will be in a slightly different location. In one case, I was cutting dog holes with a roughing pass and a finishing pass. The holes that I cut the f…

I only zero Z between roughing and finishing passes. I don’t think you can rely on consistent homing.

Sounds like a product of the infrared sensors. Proximity would have been more accurate imo. A beam of light being interrupted is not as accurate as distance from a piece of metal

My experience with homing precision: [image] 3d milling question Machines (X35/X50) This thread seems to be bouncing around a bit, but I’d like to share my thoughts on the matter of shutting down the controller versus leaving it on. When it comes to intricate carving wor…

This is about what I’ve seen. It’s a bummer, but something I can work around.

Hey Adam, [image] adamfenn28: I’ve noticed that homing is not perfectly accurate. I can home, zero the machine work coordinates, cut, then re-home, and cut the same thing and it will be in a slightly different location. I have no experience with photoelectric homing sensors as used on Elite …

Hey Adam, In addition to what @349iq2345 mentioned above, I have to ask if the the finish cut on the registration holes perhaps cut oversize, regardless of positioning accuracy? If you left, say, 0.010" [0.25mm] finish stock, then the combined X-Y error would have to be in access of 0.005" [0.013mm…

Masso advertises 10 micron accuracy of their optical homing sensors, if you are having repeatability issues on the Elite I’d look for an external source - debris in the sensor or outside sources of IR light (such as sunlight at different levels/times of the day) that might be affecting the trigger. …

Hey Espressomatic, hey Adam, hey all, anon93936469: [image] 349iq2345: But, in practice, why would you re-home during machine uptime? Homing is only necessary once after startup. True. But what Adam described could also manifest as a problem when doing multiple batches over multiple ses…

I only had this problem because the machine froze in Y. That’s a separate issue that I’ll have to get to the bottom of it it repeats. I was cutting the wasteboard, so zeroing to the home position. My finishing pass was perfectly sized. The holes that I cut fully on one side of the re-homing were…

My Elite homes to near perfect repeatability checked with dial indicators on X and Y, I did have to slow my homing speed down a bit from me speeding it up from factory settings but it repeats very, very close. Pat
