X axis stalling at high speeds
Hi
I have a second hand Microrouter that was working fine. Now, the X axis has started stalling on the first 8 inches of travel away from the home position when moved at full speed. If I jog at 2000, it stalls. If I jog at 1500 it moves fine. Once I've cleared the first 8 inches or so, I can jog at the full 2000 speed without problem. Only the X axis is affected.
What might be causing this, and how do I go about rectifying it?
Thanks

1. Remove & clean both nuts.
2. Spray slides with silicone lubericant & leave to dry for 4 hours.

Thanks for your reply Martin.
I'm new to CNCing; I've only had it for a few short months. Could you please explain in a little more detail exactly what is involved in "remove and clean both nuts" please? Or refer me to a document/website that give more details.
Thanks in anticipation.

Re: X axis stalling at high speeds
I'd try the lubing procedure here first:

This may be all the problem is - if not then the nuts could need cleaning out.
This manual should help:

Re: X axis stalling at high speeds
Thank you both for your replies.
The manuals that you referred me to are the reason that I originally joined this forum, but was sadly unable to find them; until you just pointed them out! So thanks.
I've just ordered my silicone lubricant..........

Re: X axis stalling at high speeds
Hi,
I am experiencing similar stalling issues, I have tried lubing the ballscrews and slide rails with no joy, when you mention

to what nuts are you refering too, is it the thrust coupling??Denford Admin wrote:if not then the nuts could need cleaning out.
Re: X axis stalling at high speeds
Yes. If you remove them one at a time make sure you don't swap them over & check that they are in the same aligment when you refit them as it is a four start thread.

Re: X axis stalling at high speeds
Hi again,
I have removed and cleaned the nuts and followed the lubing procedure, but I'm still experiencing stalling, even at 1500mm/m, it seems more apparent mid - 3/4 of the x axis travel, are there replacement nuts available if these are worn? Or could it be an issue with the motor?
