QuoteDancer I do not know. But there are 4 Piezos... (Standard 220 x 220 Heatbed, 4 Holes on the Edges) Most important is to wait 1 second before each probing, because the piezos trigger from the Y-movement. Pictures of the Printer to come (SD-Reader not working in PC...) I see, FOUR piezos, one at each bed corner, compensation if the two Z are out of synch, the way you attach the belt to theby MKSA - General
QuoteDancer My 3rd 3D-Printer. A Prusa Mendel i2 with Under-bed-piezos in the "cups" shown in the middle of this page: Standard Deviation: 0.001034 So you get similar if not better results with three simple piezo in a cup and a few op amps than leadinglights far more elaborate set up ? How comes ?by MKSA - General
Quotesuxfevi Hello everyone, I am currently designing a "pocket 3D printer" that I can put in a briefcase and carry with me. I am working on the design and I will try my best to fix the "flex" issue that this printer might have. However the only thing that I can't figure out is the firmware change. As the movement won't be linear, the z-axis steps/mm will have to change as the z position changes.by MKSA - Firmware - experimental, borrowed, and future
Quoteleadinglights As heard many times over the years, and just as WRONG now as then. The best sensor depends on the use: Multiple interchangeable heads, ultra-thin layers etc.. Saying there is only one best way is like saying there is only one king of road vehicle (well O.K., only the 1938 SS Jaguar need apply) edit: That was supposed to be "some kind of road vehicle" but I will leave king as iby MKSA - General

To get a better grip, a simpler way is to have a bigger diam hobbgear with sharper teeth (hardened steel) and coupled with gear reduction (regular gear or worm). A smaller motor can even be used. A light, compact extruder means also no Bowden and associated problems.by MKSA - Mechanics

Looking at your machine, I think it is the best "quality' print it can and will ever produces.by MKSA - Printing
Quotesinned sdavi- thanks for he heads up! for now i might try to go with 2 Z motors- X, Y, Z, Z1, E0 to stay at 5. recompiling will be a project for me right now. Build your machine properly with one Z motor for 2 eventually 3 leadscrews so you won't need any bed leveling and associated troubles. A cartesian machine that needs ABL is a bad one. Delta is an other kind of beast of course.by MKSA - Firmware - experimental, borrowed, and future
I guess the other belt is simply: just an idler opposite the motor, the belt being attached to the gantry and move it in Y. The point is that this cantilever approach offers no benefit here, just potential trouble. As for "accuracy" ? Compared to what ?by MKSA - Mechanics
Quotedc42 QuoteHugoW I consider buying a real smoothieboard which supposedly is the best there is, or go Homarinus' way, or somewhere in between.

You don't increase "accuracy" by using any kind of reduction gear !!!! Fact is, you are more likely to decrease it because of the gear quality. And forget about printed gears, any kind of. Digital Dentist used worm gear in combination of belts to replace lead screws for Z.

QuoteOhmarinus I really, really love the idea of being able to use the piezo since it essentially uses the nozzle tip as a probe. This technique seems to be praised as being the 'best' solution so far on many different blogs.

Quotewhosrdaddy Hi MKSA, I don't understand your comment? I was only saying that underbed piezo sensing is very difficult on a moving bed. (And it seems leadinglights might have a solution for that ) I know the smart effector but that was not my point...
