On medium speed, (the default setting), when I jog the machine all the way to the back it faults both x motors. Why does this happen? is the default speed too fast? please advise. also i was screwing in some t tracks and every time there is vibration on the table, I hear a noise coming from one of the motors a kind of soft thumping for a few seconds then it stops. nothing actualy moves but It’s weird.

Search for soft and Hard limits
You should also tells us if using Masso or redline?
ah yes redline gen two journeyman.
I believe @Woodpecker is correct, the hard limit for the back of the machine may be set slightly to far back? If that’s the case then when the machine moves to the rear, it will try to push further than it can go, then it should throw some sort of error due to the strain on the motors.
In your hard limits, try to set the max rear distance, I’d say at first an extreme distance shorter, something like an 1”. If that resolves the issue then keep creeping it back until the error pops up.
The less likely scenario in my mind is if the rails are not completely parallel, if the tightest point of the resulting trapezoid is the back of the machine, then the strain will increase on the motors as the gantry moves rearward and throw a similar error.

As to the square on the machine I am within a 32nd as measured diagonally with this instrument.
So I don’t think it is that.
