With the X Axis error, it could be a sticking home switch, clean and lube it. Also since you removed the motor/coupler it could be grid offset. Zero return, home single axis the X axis with 5he position screen visible and after it homes you should have .125 inch or less for distance to go. Great job on the trans by the way
Thanks for the info, i did try the grid offsets and i re did them multiple times on all axis but this did not get rid of the issue, as for the switch it looks brand new so i think someone thought the same thing you did Thanks Marc
Of course we enjoy your videos! They are really informative. We have a bad bearing in the gearbox due to an oil line that broke and the service shop told us to bypass the pressure safety switch and run it until they show up, of course they forgot about us and the bearing went very noisy from running dry since the top bearing(s) in the gearbox are fed by the oil pump and recieved nothing. And they say its not economic for them to take it apart cause they dont have the tools and skills to take off that pressed on pulley.... Mindblowing they call themselves a cnc repair shop not goinna lie.. And from watching your videos i was able to fix some things on the machine already myself! Altho i havent seen someone take apart a tool release solenoid to clean it, ive done that and fixed its sticking (solenoid was sticking open and erroring out on toolchanges)
Thank you Glad you videos helped you out on occasion Almost anything’s fixable but it depends on the time effort and money you want to put into it I guess Thanks Marc
@@kinzy_fabrications The noise you're hearing is definitely Gears not meshing correctly. IF Bearings became that noisy the shafts would get to a point of nearly ready to fall out.
Is there the possibility that the motor is meshed too tight or too loose to the transmission input gear? There is a bit of play there when assembling the two together.
No i think its just the burred/damaged gear causing the noise as the bearings are located in machined housings both ends of the shafts so the mesh would never change in regards to shaft location
I'm subscribed, and I find the videos interesting, but not directly useful, as I don't have any Haas machines, but cnc repair is still cnc repair - it's all similar in the end. I tend to focus on the electronics repairs more as I'm an EE, so the electronics repairs come easier for me. Currently working on a CNC lathe that someone gave me because the spindle drive blew up. Pretty sure I have all of the original issues fixed now, and now it's just complaining that I don't have 3-phase power to feed it!
Well thank you for subscribing to the channel, the electricons side interest me as id like to offer services for fixing servo amps and vectors drives myself in the uk but i have a LOT of learning to do if i want to do that myself lol All the best with the lathe drive repair Thanks Marc
@@kinzy_fabrications From my experience fixing a few machines now for myself, and at least 3 machines for others, you need fairly extensive electronics design skills to fix this stuff, because there's no real documentation available (like schematics). So you're pretty much on your own, and the issues tend to be either really easy (like bad caps in the power supply), or very difficult, requiring reverse engineering chunks of the drives which takes a huge amount of time and then bench testing things at a very detailed level to track down very obscure, or downright misleading faults or alarms. The drive I'm working on for the lathe is reporting "regen resistor overheat", but the spindle drive doesn't use regen resistors, it regens back to the 3-phase line input. Tracing out the circuit, they've tied the "regen resistor overheat" alarm to the spindle motor overheat sensor, but also at least 3 other fault detectors, because they had limited alarm signals to choose from. So that one alarm code can mean at least 3 different things, with no indication in the control what it actually is. Fun Fun! There's also a definite culture of the few people that have spent the time to reverse engineer the hardware to figure things out will NOT share any information, as they're all protectionist of not having too many people know how to fix things, and CNC techs charge outrageous prices to not even fix things properly, and just play "randomly swap parts", and charge even if the issue isn't fixed!
Getting people to watch is one thing. But, getting the same people to Subscribe is something else. It is a bit of a tough gig trying to keep the interest to make videos when you have a feeling that it's becoming pointless compared to focussing on the work you Should be doing ?? I have plenty of things I would Love to share. But comparing watch count together with Subs it seems better to stay focussed on the customer jobs than an interest in making videos 👍

I enjoy watching because I know I'm gonna need the videos one day 😂
Thanks for watching and hopefully if you do hit any issues i have covered it will help you out
Thanks for the update Marc.
I like to update even when it’s not going to plan lol
Sounds like bad bearings @ 3:41
Wow, you sure torn into it lol
All bearings were brand new and felt good when I installed them so just the bad gear teeth I think
