Re: Obtaining Dimensional Accuracy of Prints With Rostock Max v2 - 8 years ago
I think printing a cylinder is not the best way to calibrate a delta, I'm struggling a bit with this my self. I have found this: and this: Now both those are for Marlin and I have not yet been successful, but as I understand now I got the instructions somewhat wrong and have not found the time to redo. Hope it helps.by Koenig - Delta Machines

Quotethevisad QuoteKoenig I'm in the same situation myself and I've found this: It also seems one of my towers is a bit off, my prints come out a bit skewed. I thought getting the aluminium-corners would help against this, how wrong one can be...

Quotejanpenguin Increasing length of diagonal rod reduces printing size. Decreasing length of diagonal rod increases printing size. New_diagonal_rod = measured_length / target_length * old_diagonal_rod For example, you print a 50.00 mm x 10.00 mm x 10. 00 mm cube. Quote1st iteration Measured length of the cube is 49.80 mm in X when diagonal rod is 203.00 mm. New_diagonal_rod = 49.80 / 50.00 *by Koenig - Reprappers

So I've been using M666 (endstops), M206 (Z-hight) and M665 (deltaradius) to calibrate bed level and is fairly pleased with it for now. But my prints are dimensionally inaccurate so I have followed this guide: Printed a 50% version of the asterisk he links to on that page and from how I understands it you should measure each line starting closest to a tower and moves away from it in a straightby Koenig - Reprappers

Quotetadawson Crazy idea, but an easy test. I take it your electronics are under the bed, correct? Try laying the printer on it's side, and perhaps a small fan blowing at the RAMPS card, and see if it will heat. A bad solder joint set off by thermal expansion could cause your thermistor to glitch. If that works, edit pins.h and put the thermistor in question (E0) on the unused thermistor input. Yby Koenig - Delta Machines

Quotellamatrails QuoteKoenig Could be firmware as well. "Heater_ID: 0" that is the extruders hotend right? agree on that? It doesn't matter what temp the hotend is, I've tried having it at room-temp or heated to 235C (also read in pronterface, reported by marlin) but when the bed-temp reaches ~80C I get that error, sometimes before 80 sometimes after. Highest reading I got from the bed was 89.by Koenig - Delta Machines

Also what do you guys says about this: The dimensions are way off here, much more than a small tower displacement.... It is supposed to be an asterisk with the diagonal lines running parallel to each tower, with a horizontal line through the centre. The firmware I'm using is 1.0.3 dev from 2015-06-09.

Quotetadawson How do you know you are at 80? Is that coming from Marlin, or are you reading it yourself?

Heater_ID: 0 Error: Printer halted. kill() called! Error: Printer halted. kill() called!" Any ideas what it could be?
