Re: plans & parts list for a delta printer - 1 year ago
Quotemasterviana The 3mm holes I think i can deal glue a paper printed whit the holes, the countersink its a bit more harder for me never done that job before. The "countersink" deep its only based on your expirence there is no way to mesure the deep. which countersink bit you've used? Even if dont countersink the holes the print area of the bed its only 300mm and the bed had 330mm, that gives 30by dc42 - Delta Machines
Re: plans & parts list for a delta printer - 1 year ago
Quotemasterviana From a while i've been looking to your build as an example for a well desgin delta, the only thing that keeps me from moving forward for a build is the fact of a alu bed. You have machine your 330mm 5mm alu bed. I wouldnt risk that job by myself, creating the holes and "countersunk" the holes. It's not difficult to drill and countersink three holes in aluminium.

Re: Twin nozzle - 1 year ago
You are correct. Likewise you don't need to set up tool change scripts in the slicer, because any operations needed such as retraction and repriming can be done in the tool change files.by dc42 - Ormerod

The updated version of the second link that Robert posted is . Be warned, delta printers that print accurately need to be built precisely, so they are not cheap to build. However, a good CoreXY build probably costs more.by dc42 - Delta Machines

We've seen a few issues when using Safari. You could use whatever developer or debug features Safari provides to get a trace of what is going on, perhaps also a Wireshark trace, and post those on the Duet3D forum.by dc42 - Firmware - experimental, borrowed, and future
Re: Rostock Max V2 with Tricklaser Arms, Calibration Woes - 1 year ago
I suggest you post your height map after auto calibration and mesh probing. That may give us clues about the nature of the problem. You will probably get a faster response if you post on the Duet3D forum at . Another good trick is to mount a circular spirit level on the effector,.to see whether the tilt varies with XY position.

Re: Layer Shift in Y axis - raising Y axis current - 1 year ago
Motor torque is approximately proportional to current, until the current gets so high that the iron saturates. Most stepper motors are rated to at least 80C. Does the motor have a label on it? If so then you may be able to look up its data online and find its rated current. Check that you really are running in spreadCycle mode. Layer shifts are far more common in stealthChop mode, because stealtby dc42 - General

Re: Kossel Delta xxl build project HELP - 1 year ago
I just looked at your tuning results again and it appears that the heater power is too low to reach the target 200C. That points to a bad heater cartridge, bad connection, or low power supply voltage. It could also mean that the temperature sensor is greatly under-reading, however that should not be the case if you are using a PT100 sensor and you get the correct reading at room temperature.by dc42 - Delta Machines
Re: How to change configuration to a delta robot not a printer? - 1 year ago
You need to run firmware that supports Rotary Delta kinematics. RepRapFirmware does, see . Maybe there is a fork of Marlin that does. The calculations for Rotary Delta kinematics involve trigonometry, so you should use a controller with a fast processor and hardware floating point. Calibration can be tricky because there are so many parameters to set - not a problem for a well-manufactured commeby dc42 - Delta Machines

What is the hot end temperature limit set to? Send M143 H1 to check it.by dc42 - Delta Machines
Re: Kossel Delta xxl build project HELP - 1 year ago
It looks like the gain of the hot end heater has reduced and the cooling rate has increased. Were you perhaps tuning the hot end with the print cooling fan off last time, and on this time?by dc42 - Delta Machines
Re: Marlin 2.0 for delta printer - 1 year ago
I can't comment on Marlin, however I think it likely that your ABL issues are caused by the combination of imperfect delta geometry and your use of a Z probe that is offset from the nozzle. Many types of geometric imperfection in deltas cause the effector to tilt slightly with XY movements. This tilt causes the relative height of the nozzle and the Z probe to change, which causes errors when youby dc42 - Firmware - Marlin

Re: Strange behavior during PID Autotune - 1 year ago
I'm glad you got it working with RRF. BTW, the latest RRF 3.2RC tunes with the print cooling fan both off and on, so that it can apply feedforward corrections to the heater power when the fan speed is changed.by dc42 - General
Re: Kossel Delta xxl build project HELP - 1 year ago
The tolerance on typical Chinese heater cartridges is very wide. You need to re-turn the heater after changing the cartridge, even if the new one has the same nominal power.by dc42 - Delta Machines

Re: Hotend Temperature dropping - 1 year ago
This is why we implanted feedforward heater control in RepRapFirmware.This temperature plot shows the effect of turning the print cooling fan on at about time 18, and off again at time 106. To reduce the amount of temperature drop, use a silicone sock on the heater block, and make sure the air is directed at the print not the nozzle or heater block.by dc42 - Delta Machines

Thanks for pointing out the error in that paragraph. I will correct it. Further down in that page under "Homing files", it says: QuoteFor each of the proximal and distal joints, you should have a homing switch either at the maximum limit (maximum anticlockwise angle as seen from above), or at the minimum limit (maximum clockwise angle).
