I am gaining huge respect for people how work with wiring looms. This is one is small but getting the lengths right and where to break out etc is a challenge.

EDIT: Each wire length is 3.5m

I remember doing a exam in my youth for wrapping looms up with like string stuff, I was pretty good at it as well.. no idea these days. Bodge tape is my friend ;) or cable ties if I wanna go pro :lol:

The loom has broken through to the underside now. Time to do some crimping for all the connectors. All this effort to eventually print a complete STFM case, but its been fun building :)

Well thats me done on the Giant Panda for this weekend. Got it to the point where the print bed is now in place and the X & Y axis work correctly. The Z doesn't yet as the probe is not wired in.

Things left to do - Wire in the bed heater and thermistor, put all the connectors in for the tool head and then prime the V6.Finally need to do the panels, fans and extruder.

Update on the printer.

Print bed heater is wired in and hotend tool is in place. Just need to finish wiring in the connectors on the head and then its all down to sorting out the firmware settings and calibrations.

I did try levelling the Z axis the other day only to find out the probe I had was defective. Fortunately testing with a sheet of metal above the print bed allowed me to turn off the printer before the head moved to near to the bed.

What Z-probe are you using?

It's built into the X,Y carriage system and is a PL-08-N2 - http://www.cheemi-tech.com/pdf/Cheemi%2 ... -PL-08.pdf

Whilst they are not at all bad, their performance is influenced by heat and so is your build plate. If you find inconsistencies it's a good idea to swap it for a BLTouch probe. They are an expensive swap out, but really are worth it for your sanity, especially if you use different filaments that run at different temps. I was tearing my hair out on my printer that is used for PLA and ABS, the bed would warp differing amounts because of the temps and the probe would also be affected by the increased heat of the bed by up to .5mm when printing ABS, meaning getting the two filaments to print one after the other was a pain. The BL touch has tolerances of less than 0.005mm which made it all 'fire and forget'.

You may find that inductive probe is fine though and I do use them successfully on other printers, it's just a thing to look out for if you are having issues.
