Quotelolocaledo Hello, The last thing I have to setup is the scale. What is the parameter to modify to have a correct scale ? If your size is wrong on all axis XYZ then you steps/mm are off, if your size is correct in the z-axis but wrong in the XY-plane then you need to adjust the "L" parameter of the M665 command.by Koenig - Delta Machines
As for the FolgerTech metal corners there's a thread dedicated to bashing the quality of them, also in the FT kossel thread they are mentioned in a not so good fashion. The Robotdigg metal corners is of much higher quality, there's also some "simple" metal brackets in the works: I'm planning on ordering a set of those for my slightly larger delta build.by Koenig - Delta Machines
QuoteTha_Reaper talking about currents... i just realise ive never even adjusted those. just plugged the drivers in, and started moving the printer. Is there a guide on how to find the best current for a delta printer and set the drivers accordingly? I dont even know what a too high a current or too low even does (except for frying your steppers, or overheating the drivers) You should adjust theby Koenig - Delta Machines
QuoteHephaestus0000 Is that it? I"m so tired.,,,,,,, That's what I meant. Try turning off "Retract on layer change" and see if that helps. Then that picture from S3D seems to look like your problem as well, overheating, that might come of that you're trying to print a small piece at high speed, the layers do not have enough time to cool down before next layer is beeing put down.

Quotelolocaledo Dear n8bot, I noted in your different posts tha you use Duet0.85 with Simplify3D. It's my configuration. However, I got to some difficults with S3D and temperature control. If I define Bed temperature and hot end temperature in S3D setup, when I launch the printing, hot end and bed don't warm up. I have to define and start the hot end's temperature in the webinbterface on the Duby Koenig - Delta Machines
Quotenebbian Cripes, no need to drop that sort of dough. Something like this would do the job: http://www.jaycar.com.au/Electromechanical-Components/Relays-%26-Accessories/Panel-Mount/Heavy-Duty-Chassis-Mount-Relays---30A/p/SY4040 It's mechanical, so it would probably wear out rather quick + plus it would make the printer noisier.by Koenig - Delta Machines
Quotelolocaledo Hi all, To be sure, what are the M666 parameters when I measure X,Y and Z tower : X -0.35 Y +1.10 Z -0.95 I am tempted to say M666 X0.35 Y-1.10 Z0.95 is it right ? After reading many posts, it begin to be confused for me :-) Depends on which firmware you are using......by Koenig - Delta Machines
Quotedc42 If the printer is louder since uograding to the Duet, the most likely explanation is that the motor currents are set higher. I haven't heard that the decay change makes any difference to noise when using A4982 drivers. I run mine at lower current with the duet than what I did with ramps and a4988 and 8825's, it's still louder + it got a different "singing" to it. I have never modifiedby Koenig - Delta Machines
Quoteo_lampe Magnets with radial magnetic orientation instead of the common axial orientation would be best in terms of magnetic flux. But I haven't heard of such, yet. -Olaf Isn't it better then to place the magnets in the rods and the balls on the effector? Like Haydns solution.by Koenig - Delta Machines
Quotedavidf01 Can anyone tell me where the measurements are taken for: DELTA_CARRIAGE_OFFSET DELTA_EFFECTOR_OFFSET I measure from what point to what point for these two settings? Thanks Do keep in mind that the "DELTA_EFFECTOR_OFFSET" is an imaginary point between the rods in a pair. However, both these measurements don't really serve a purpose, the only interesting measurements in that picby Koenig - Delta Machines
Quotehacker QuoteDRTak Hacker. Why is your kossel loudER now with duet? I'd love to hear expert opinion myself. I attribute it to the lack of segmentation for now — after all it affects how it moves and therefore the sound it produces, but I'd love to hear expert opinion. I chalk it down to the fact that they have implemented the "decay hack" on the drivers.by Koenig - Delta Machines
Quotepaul_delta Quotethevisad So many men so many minds. With paper test It's very hard to get accurate calibration. Even more - for delta this is completely wrong way, because the chances to crash the head are very high - there is no safety room. Now you have an airgap, second later you have unneeded deformation of whole system. The drillbits give you a room to work, they have zero deformation uby Koenig - Delta Machines

Quotepaul_delta Tip: forget about paper test - it is not accurate enough! Use drill bit - roll it under the hotend tip close to the screw and adjust the screw so the drillbit will roll just slightly touching the tip. Don't say that, I just people put to much into it. The paper test is just a feeler, what you want to do to get it 99.9% right is: finetuning after the paper test. But then again alby Koenig - Delta Machines
Quotedavidf01 I wouldn't mind switching to Repetier but there is no information on how to set Repetier up on this printer. Everytime I try i get results that are unusable.

You flash the repetier firmware, you can use the same settings as you have but some of them are not named exactly tby Koenig - Delta Machines
Quotepaul_delta QuoteKoenig No need to go through that to adjust your steps/mm, if nothing has changed FT includes 20tooth pulleys which corresponds to 80 steps/mm with 1/16 drivers. In that guide they use printed pulleys which is why they do travel and measure, since this kit includes metal pulleys that is not needed.

Quotelolocaledo Hi all, Perhaps a basic question for you : The head fan have to be always on however when I connect on Web control, the Fan Control is 0% and I have to set it up manually to 100% How to fix that parameter ? You should probably wire your fan (hot-end fan?) directly to the 12V supply, the fan control I believe is regarding a layer-cooling fan which can be controlled via the gcodeby Koenig - Delta Machines
OK, so you have ruled out retraction, that is one thing less at least. You say it came out worse when you printed last time, how? Is your extruder calibrated? What does your slicer setting look like?by Koenig - Printing
Why not wire them directly to the PSU?by Koenig - Reprappers
QuoteHephaestus0000 Quoteborupdk Try to print the object without any kind of retraction, I have a hunch that would almost eliminate your problem. At my intended speed goal or at a lower speed? Start at lower speed and when you get results that is acceptable to you - raise the speed.by Koenig - Printing
I personally don't have any experience with this type of printer but to be able to print at 100mm/s I think you need a printer with a lot less moving mass, like a delta. Maybe someone else knows the upper limit for accurate printing with a prusa style printer? But I'd try much slower first, like 30-40mm/sby Koenig - Printing
