Thread: y axis stall e05-0303

    Default y axis stall e05-0303

    While finishing my last project I received the y axis error, now it is firmly up against the keypad. I had the brushes and bearings replaced about year and half ago and only have used the machine less than 50 hours.anyone's input would be appreciated

    You can try re-adjusting the Y-belt first (loosen the adjustment screw, then re-tighten. The built-in spring adjusts the belt tension automatically when you do this.)

    If that fails, clean the rails thoroughly, check that the bearings are rolling freely when the y-truck is slid manually side to side with the power off. If a bearing is seized or intermittent, lay some towels on the traction belt, spray the bejeezus out of the offending bearing with WD-40 until it can turn freely again.

    I would say check the Y-motor shaft for wear, but with low hours you mentioned, that’s probably not the problem.

    Not moving at all as you know is not good. Do you have the 12mm wrench that is needed to adjust the bearing? You can grind one down to get it to the nut. There is most likely a tread locker used on the bearing screws. A pen torch is handy here to heat the bearing retaining screw to a temp that breaks down the tread locker. I see 50 hrs since brushes and bearings, how many machine hours? The Y axis gearbox could have lost a bearing as well. With the belt loose drive gear does the truck move? If not then the Y truck bearing could be the issue. If it moves then the Y axis gearbox is looking to be the culprit. The Y axis gearbox can be rebuilt,but I believe LHR only sells new. The shafts are available through a third party here on the forum. I have the smaller bearings for sale fairly cheap. The newer gearboxes have two bearings of different size. I have not yet gotten the size of the larger bearing so I do not have the larger one for sale only the smaller of the two. Older models have two of the smaller ones that I sell. The shafts are being called Tim shafts as Tim is the guy making and selling these shafts. I have a few of them from him so if needed I could get you his info.

    Machine off, disconnect the flex shaft and then try moving the truck before doing anything else

    Before you loosening the Y bearings try taking the Y belt off the tension roller (far right side of the machine) and see if the truck will move.
