So – after stripping and re-assembling the shafts making sure everything was true and modifying the belt clips slightly so that I can put a small cable tie around the end where the belt comes through to make sure there will be no slipping, I finally have a printer that is working :).

I am super pleased and can now go about the final calibration on the spreadsheet and then fine tuning the extruder feed and retract settings.

Thanks Q :).

Thanks Quentin. Will see if I can find anything and will report back.

Hi Quentin.
I am battling to get the machine calibrated now. Perhaps you can point me in the right direction?
If you have a look at the calibration print below – the x axis is making a very narrow fill and putting the outline away from the fill. Even putting the dimensions in the spreadsheet and taking the new values doesn’t fix this. I can’t seem to find the issue. Have you come across this before?
Just for reference. The pic is taken with the bottom of the piece facing up (so it’s upside down)

So what was the counter for?

So – A quick update on the progress. After struggling with the extruder jamming, I eventually figured out that the filament was extremely tight in the hotend. After some research and eventually stripping the hotend down I figured out that the brass nut in the back of the hotend had been put in way to tight and it was squashing the PTFE tubing in the hotend. This was restricting the movment of the filament through the hotend. With this finally fixed I got impatient and had to print something – it printed – its ugly, but it printed :). I now have a lot of calibrating to get done to get it to where it should be. And I need to figure out how to get the auto bed leveling working as I am using Yogi’s firmware, so manual leveling is out as he removed it from the firmware.
I have printed a small servo arm on the other printer, so will see if I can get that mounted somewhere for the auto leveling. Also need to get the calibration finetuned on the extruder and also on the X and Y steps. So the next print will be the Morgan calibration print.

Can’t seem to get the video loaded into the post – So here is the external link.

A quick update – Machine basically assembled and testing with a dry print – hotend and extruder not attached yet.

All working well, so now final assembly and calibration before we run the first actual print on the machine.

[heliknight]

Ok. Build coming along nicely now. Hopefully will be able to start calibration in a week or so.

Hi Quentin,
I spent the day cutting the dxf files on the cnc and now i see the holes for the z mount top and z mount bottom don’t line up with the holes on the platform or base.


Are there new dxf files for the base and platform to accommodate the printed z mount brackets?

[heliknight]

Thanks Quentin.
And some more parts printed…
Coming along nicely now 🙂

[heliknight]

Thanks Quentin.
Here are the pics so far.
The modified CNC doing its thing…

My completed parts so far… (now for all the big ones!)

[heliknight]

Seems the pics I added above are not showing….
Quentin – Can you help?

[heliknight]

Thanks Quentin.
I will make the first one 420mm and then we can make it bigger if needed.
I am still printing all the required plastic parts on our modified cnc machine at the moment. As soon as I start with the actual build I will post progress.
