needle height calibration always crashes software

Hi, I have the machine built and all limit switches tested. When I initiate the "needle height calibration" the needle correctly descends until the limit switch triggers, then backs off, then prompts me to "Jog Z axis until the needle just barely touches the PCB then click Next"....

Re: so far so good...

Day four: motion on all four axes, all six limit switches checked and working. More notes: - It would be useful to mention the phenomenon of "motor stalling" earlier on. What is this, anyways, and why does it cause the *software* running on the TinyG's microcontroller to crash? This caused...

Re: so far so good...

Update, start of day #3: all the mechanical assembly tasks are finished. A few more minor comments: - Drat! I wound up at the last step with two extra M5-8 screws and lacking two M5-12 screws. Curses! The up-looking camera will have to wait. - I couldn't find instructions for mounting the drag chain...

Re: so far so good...

as long as the hole is smaller than the octagonal part of the spacer it won't matter, right? So no need for those holes to be so tight. By adding additional clearance having a hole larger than the beveled diameter would let this part to be able to diametrically move inside the hole. But wouldn't th...

Re: so far so good...

As I did not like the Z-high-limit switch, I designed a small 3D-printed part to mount it underneath the gantry - see photos below: Oh neat! Yes, that looks like a much better solution. I like it! If you have access to a 3D-printer, I will happily share the STL file - let me know. Funny that you sh...

Re: so far so good...

Ah yes, one last hint. For those in the US with our demented system of measurement, it turns out that a 4'x2' work surface is exactly the right size for the liteplacer and a laptop. So for a tabletop you can just drive to the hardware store and pick from what they have. Home Depot carries a large va...

Re: so far so good...

A few other suggestions: - It might be best to attach the luer lock AFTER completely assembling the pnp head. I accidentally ripped it off while putting the rod into the shaft, but fortunately I didn't damage the threads. - In many places the instructions say to put the extrusion nuts into the alumi...

so far so good...

My liteplacer arrived yesterday! Stayed up until the wee hours of the morning and made it as far as step "X.17: Finished Frame" -- wow, it actually looks like a pick-and-place now! The instructions are absolutely fantastic. I think any company considering manufacturing any sort of product ...
