Random Erratic Possible Stalling Problem with router

[Earle]

Hi Guys,

I have an annoying issue with my router in that it loses position with the resulting tossing of the work piece!!

This does not happen all the time and when making signs which is 90% of my work it does not normally occur at all probably because of the short duration of the job. I have been cutting some 'pixie doors' for my granddaughter and the problem is apparent as the job runs for approx. 2hrs.

I thought I had got rid of the problem as I had a faulty USB cable, so replaced with a quality double shielded one! but oh no - the job runs through the roughing stage that's takes 30min no problem (at the moment) I ran the finishing job twice - the first time it failed after 5 minutes and the second time after approx. 60 minutes. The first time it lost position on the x-axis by about 2cm I ran the job from the start again and the second time it failed it was the y-axis and it lost position by about 6cm.

I thought the job would fail at some point so videoed the second run, reading on the forum I think the stepper is stalling and should probably lower the feed rate. I would appreciate any feedback on the video of the problem!!!
