SigmaX Dial Gauge

__Edit 2021-07-10__: Clip to side-mount the gauge as front mount cannot reach the back screw. __Edit 2021-07-04__: If you d not have the original BCN3d PTFE, it may be to short as you need a 1050mm at least. I cannot find longer then 1M PTFE, thus I designed a coupler to lengthen it - the tension on the head is significant according to the dial gauge. https://www.thingiverse.com/thing:4900346 __Edit 2021-07-03__: ExtruderClipV2 Added 'fins' to the bottom of the extruder clip for better grip. Increased thread-hole size by 0.4mm Bracket for a SigmaX extruder for manual bed leveling. Uses an 8mm shaft dial gauge (digital). Requires 4 x M4 10mm hex bolts. Prints without support - teardrop 'tail' on holes should face up if positioned correctly. The extruder clip does not stay in place good enough - may need to rework it. When leveling - do the following until it is level. The first pass will always fail as adjusting the front moves the back up/down. Clean nozzle - or even better make sure the nozzle is about 3mm away from the bed, remember - this is to level bed, not to set nozzle-bed distance. __DO NOT__ leave gauge on the head when printer is on - it may smash the gauge against the frame. 1) Center back 2) Frond left/right above adjustment screw 3) repeat from 1 until level - usually 3 times. When doing a calibrate - do NOT change the bed knobs, just select accept - after second bed level attempt there will be a 'skip' option to continue without automatic bed level. I have also found - using the dial gauge that the PTFE tube 'pulls' the head on the 'other' side of the build platform - as much as 0.3mm - this is why the bed level is always a problem. Need longer PTFE tubes. than 1M
