Quotefrankvdh 20mm seems to be a very large value for the screw pitch. Are you sure about that? 100% sure. This is not a small printer. The print volume is over 4m³ We are using a geckodrive as an external. Will the microsteps come from the external, or the onboard?by Vital1 - Mechanics
we are struggling to calculate steps per min on our z axis (with a lead screw with a pitch of 20mm) The onboard driver is 16 microstep, but for the z axis we are using an external driver that has 10 microsteps which runs a nema 34 1.8 with a 50:1 worm gear We have followed formulas, and also an online calculator, trying with 16 and a 10 microstep, and tried the values with no success Are we missby Vital1 - Mechanics
Yes it is the volcano hot end. printing at the 'normal speed' there is a problem with the layers sticking. And when tweeking the extrusion multiplier, it just gets clogged up (have also changed the temp as well) The normal speed is 65mm/s sometimes 70mm/s, but with the large nozzle, I have managed to get to 40mm/s with a layer height of 0.7 which provides a workable finish.

People say that if you print with a bigger nozzle, the print time decreases. In the past we have used 0.4, 0.5, 0.6mm and 0.8mm nozzles, and each time the time has decreased as we increase the nozzle size, and actually increased the speed very slightly, and got quite similar finishes. We normally print with a 0.8mm nozzle, but recently got a 1.0mm & 1.2mm nozzles, and have been using numerousby Vital1 - General
We are in the process of building a large 3d printer - a build space of 2.2x1.2x1m. We are now putting together a shopping list whilst the frame is being built, and it looks like we will be using a Duet board, either Duet V0.8.5 or the WiFi. Due to the size, we are possibly looking at Nema 23 or even the 34. Are these motors compatible with the Duet boards ?by Vital1 - Duet
