This is work done a couple of days ago but hopefully I will continue it tomorrow and get back to printing soon. The pictures should help but I will put together a full account if they parts work. I must admit I am unsure of the bearing and block as being a possible weak point. I have a stronger design in mind but this will require changes to the MDF parts. If I do need to make such changes I intend to use the SumPod to mill the MDF.
I have also made a couple of new nozzles, one with 0.3mm and the second 0.5mm holes. Also they have a heating chamber where the PTFE tubing is not heated directly like the present one. Again if it works I will write it up and give a drawing in the download page.
Any questions then please email me.
