The x axis positive rapids have developed this loud jerky sound with occasional visible snags. Same to a lesser extent on z retract rapids. I’ve noticed a lot a dirty grease on the respective axis, so dirty in fact it’s kind of solid in places. This machine gets a lot of use on literally every kind of stock from tool steel to MDF and plastic so perhaps it’s not unreasonable to assume something got in to the screw mechanism.
I figure the best option to start with is clean the lead screws and add more grease. I’d really rather not dismantle the lead screws so if anyone has other options I’d love to hear them.
If it turns out I need to do that I’d appreciate a walkthrough on how to do that without messing everything up.
