Quotecman8 Just spread out my parts. Looks to be complete. I did get the 36 tooth not the 20 tooth. Do you guys suggest I order the 20 tooth instead? Also what are most of you cutting your rods at? I know a lot of people have been saying the length on the manual is no good. Is this the case? It is really up to you to decide but I recommend the 20T pulleys as they give more resolution at the expeby mmcginnis9272 - Delta Machines

Quotejculver09 Thank you mmcginnis. This answers just about every question I had about setting these up. The geometry of the effector and carriages is what I think the calculator I mentioned is missing. So you would recommend I order 200mm long rods (I am assuming this is still measured center to center on the balls). I may order them from him or make them myself because he has a 3 week leadby mmcginnis9272 - Delta Machines

I've printed about 3 KG of filament through my machine with the mag effector setup and so far I see no noticable wear on the sockets, and I haven't even lubed them like I thought I should. I simply forgot to and they are still holding up fine. Haydn prints them in PLA. I noticed a dramatic increase in print speed with the longerby mmcginnis9272 - Delta Machines

Quotejculver09 There is a calculator posted earlier in this thread (posted by vorpal on page 13). I dont think it is 100% perfect for predicting the outcome, but at first glance it seems to be close. I planned on measuring my current setup, checking it against the calculator, and using the difference I find to give me an improvement on the calculators prediction to determine if it is worth it toby mmcginnis9272 - Delta Machines

I realise that the build manual has the RAMPS and Arduino boards installed underneath the heated bed but, as has already been tried on this forum, would it be better to position these on top of the frame and away from the heat?

I increased my stepper voltage to .65v to get it to feed well. Since the Extruder motor is larger than the other 3 motors, the extra surface area dissapates heat better, it can handle more current and stillstay cool (The Folgertech manual voltage adjustment should be higher for this motor). You could even go higher than .65v if needed. The only risk you run is having the Polulo driver board geby mmcginnis9272 - Delta Machines

Re: Folger Tech Kossel Delta 2020 Full 3D Printer Kit w/Auto-Level - 11 years ago
I noticed that if you use Repetier firmware, the motors run one direction and the Marlin firmware runs the other. One solution is to reverse the stepper motor connector so the red wire is on the power supply side of the board with Repitier and the black wire is on the power supply side for Marlin firmware. Annother solution is to just set the direction of the motors in firmware.by mmcginnis9272 - Delta Machines
