Lost calibration

Tue Feb 13, 2018 12:38 pm

I am at my wits end trying to calibrate my printer. It had been working fine but it got knocked so I thought I ought to check the calibration.
Since the knock I get calibration failed consult the manual as the error message.
I have checked the alignment several times and currently I have the Y axis set distance at 99.91 on one side and 99.94 on the other. I have checked that the Y axis is parallel to the frame, I have checked the belt tensions on both X and Y axis I have checked the pulleys are tight the bed is screwed down tight. In fact I've checked just about every screw on the printer. firmware is 3.0.10.
This is currently a very expensive ornament, please help.

Hi Duncan,

having the latest firmware is a good starting point,
doing a factory reset ensures that the firmware is in a known status,

Is it possible that the Y axis frame has become twisted?

with the printer on a smooth level surface? Try pressing alternate opposite corners down.
to see if the frame rocks at all.

ensure that the aluminium main frame is located correctly, with the screwed threaded rods located in the bottom of the cut outs, so that the aluminium frame is suspended in mid air... not resting on the table,

using the Control knob on the front panel raise the X carriage to the top and make sure that you keep in raising the 'Z' height until both Z motors stall because the X axis has reached the Z axis end stops. at the top of the frame.

then when all is ready, make sure the extruder nozzle is clean, and do a fresh self test and XY calibration then a Z calibration, then set your Live 'Z'

best wishes, Joan
