High-Lift Z endstop for iMakr STARTT and TronXY XY-100 for Coprint / Chromahead

As part of our plan to upgrade our TronXY XY-100 (also sold as iMakr STARTT) printer with a CoPrint system it was necessary to move the Z endstop up by quite a large distance in order to accommodate the considerably larger Chromahead that the coprint system uses. This end stop moves the Z switch up and provides some more adjustment and more stability than the original.

We've supplied this in 2 versions, one made for use with heat-set inserts and one made with nut wells for standard bolts. If you're using the Klipper upgrade carrier then it's a good idea to use the heat-set insert style as there's not much room behind the Z-endstop and bolts might short against the PCB. If using the original printer then the bolted one should fit fine and will save the cost of the inserts.

Printing recommendations

It's best to print this in a very stiff filament, so PLA or fiber reinforced ABS/ASA should work well. I'd advise against plain ABS or PETG as they might flex too much for accurate operation.
