I feel your pain. I was replacing all the bearings on my 1997 Acra bedmill and when I got to the gearbox it appeared that it needed to pressed out. I didn't know it just simply slipped out after removing a splined shaft (shifter). Needles to say, I broke the casting. I tried to remedy it, but the 25+ years of oil soaked casting was not having it. So now I am converting that head to a cartridge spindle from an old Haas. Great video, new subscriber, thank you for posting videos of you tackling machine repairs.
15:58 regarding the x axis too large error. Whenever I see a fault from a cold start which improves the longer the unit is turned on I always suspect electrolytic capacitors. They lose their capacitance with age and this is accelerated if they are in a hot environment. You then get comparator circuits which detect over currents etc being tripped by signals which would be within limits if the capacitors were smoothing the signals correctly.
Hi Thank you for that information, im not sure where to look for these specifically though as i have changed motors, servo amps and even mocon boards etc so would of thought one of those would have solved the issue unless i was unlucky to have the same issue on 1 of my spare parts Thanks Marc
Always Wise After The Fact 👌 What's new. That's life in general. We know so much after we learn how ?? But it takes a few things for this to happen. Maybe like you mentioned the guy over your shoulder with a different view of things is good. ( usually, it's a mate with good intentions but has no clue how to even change a light bulbs giving you advice 😅 ) Otherwise, it's a case of leaning from experience. Either you pay for this experience. Or you do it like most of us. Learn the hard way ?? After the disappointment and some frustration of doing it the wrong way, you learn something you didn't know before. At least you're lucky to be in a position where you can fix your mistakes. Otherwise, like most, it's an expensive experience. Live & Learn 👍
Is there a cvar value you can change in the settings for that sensor to increase the time it waits for the signal from the switch? It may be that the mill is not waiting long enough for the switch to return good to the controller causing it to error out. Someone may have altered the start up routine when the switch went bad the first time. As it works after initial powerup it would seem that it's a wait state / software issue - not a hardware issue.

Yes sometimes we learn the hard way but you can’t buy experience as they say lol
Thanks for watching and subscribing 👍

Exactly
Luckily I know a man who could machine something to fix it lol
thanks for the video

Love the vids BTW!
Hi
Do you mean for the X axis home switch?
Sounds better Marc. Great work there
