Hi TTN,
Thanks for the encouragement on my Delta-Pi Prototype. There are a few under construction around NZ and Australia. One in Auckland is doing a lot more printing than the prototype has. I had my own design of hot-end on it and it kept giving me problems and jamming on the PLA.
I've just got myself an E3D hot end to trial and I have high hopes for this.
I've also implemented a bed levelling probe like Johann's. That seems to be working well but the proof will come when I have the new hot-end installed.
One thing I will point out is that Delta-Pi uses Stainless steel tubes. 3/4" (19mm) or 20mm. The problem with using Aluminium tube as a bearing surface is that the soft aluminium surface is so easily damaged by dust and dirt and once it gets damaged it quickly deteriorates to the point of being useless.
The usual solution is to use rollers made of something even softer than the aluminium eg. delrin. But I preferred to stick with a hard steel surface and the polished stainless tube is cheap and readily available.
