Re: Automatic Tool Changer
After doing some more R&D on the tool changing, perhaps there's a better way to change a toolhead than simply prying it off via plastic at the tool holder location, especially if the magnets are...

The Cherry Pi III and Griffin seem to be the most active new designs, with the Kossel (both 1515 and 2020 variants) being most popular. My next printer is a toss-up between a CoreXY or a Delta based...

Thanks you ! :) "your frame is misaligned or twisted.. check all the diagonal measurements and get them eqaul.." how much accuracy needed? in micrones?
View ArticleRe: error/difference between x and y axis in delta 3d printer
0.1 -0.2mm error is acceptable but try to get it equal.. or live with x-y error... try printing a large cube 100 x 100 and see the error if it is percentile or absolute

You should definitely be using it with the thermistors. They won't get as accurate as they can get without it. The hot end heater will be more efficient with thermal paste too but a tight enough fit...

I think the mini kossel is the most active delta at the moment. the 1515 version is ok but not stiff enough if you make it bigger than the stock size. The 2020 variant is very stiff at a reasonable...
View ArticleRe: error/difference between x and y axis in delta 3d printer
It is a delta. X/Y/Z errors are all tied together. It is enough to perfectly level the bed the old way and also your X/Y dimensions will be correct (or at worst all scaled by the same constant). And...

If for example you use the fan header on the printer. Wind a couple of electromagnets small enough or take apart a small solenoid and use those parts you could have a very low friction high precision...

I am trying to find the max current on the fan header on the Ramps board so I can determine how many turns of copper wire and what gauge of copper wire to use because I don't want to pull too much...

With the GriffinPro we are running the Axteeg X5 mini with FSR for auto calibration and optical end stops. Right now we can push some amazing speeds and still get quality prints. The nice thing about...

Unless you weight the end effector down greater than the force exerted by the extrudate, the extrudate will have a lifting force in the Z-axis.

understood, my initial plan is to have a 8' cubed printing area, with 2 full reals of material as counterweight on the extruder. The guide lines i also have a plan for to move power and data on, but...

To my understanding, only one type of extruder fits on this printer due to the center pivot. Someone could maybe look into a center plate with virtual pivot point hinges. In this way, a clean platform...

My old Marlin configuration.h file has this little gem hidden inside it: // Deltas never have min endstops #define DISABLE_MIN_ENDSTOPS Since M119 isn't showing the MIN endstops, I'm guessing that...
