OK, over 170 views and not a single comment. My interpretation is that there is no interest for discussing 3D printers on this forum, or no interest for my printer. I have no problems with that, so don't worry, no need to post comments just to bump the thread to the top. Anyway, since I made some more progress, I thought I post my second view here as well, in case somebody is interested to watch it.
It is about my Y table, which is made out of 3mm aluminium plate, using 2 x MGN12 rails with four carriages and 10mm wide GT2 belt driven by a 0.9 degree, 1.7A stepper motor. Everything mounted on a 3mm aluminium sheet. The modular design for was my aim from the start for easy installation, change and adjustments.
