Will do, thank you!

Repetier said: I know someone had the GLCD working on the expansion port without levelshifter at all. Maybe that works better for longer cables. Hey Repetier! That was THE remark I needed to get things working well. I tried both this sol…

Link?

Repetier said: So you are saying the method is working good. That's good to know. I once implemented a autolevel method and spend a week with it and removed it for not being stable. So did not want to waste again such a lot of time. I wo…

Hey Repetier, I am trying to revive this thread as I still do think that implementing dc42's way of calibrating a delta (http://escher3d.com/pages/wizards/wizarddelta.php) would be a killer feature in Repetier firmware, especially on 32-bit boards (…
-
I see, ty very much for the thorough explanation!
-
Thanks, that'll do!
-
Also tried it, but can't get it to work. It connects to the printer all fine, but I can't send any commands nor can I disconnect or do anything else.
-
Any chance that this will find its way into the next release? Would be quite the killer-feature still.
-
Ok, got it. Will comment it out. Thanks again!
-
Perfect, thank you! Display in use is a standard Reprap Discounts Full Graphics one (on a Wanhao DI3). FEATURE_CONTROLLER 11 (ui.h: Line 630) The only functions using UI_RESET_PIN are: UI_KEYS_INIT_BUTTON_LOW(UI_RESET_PIN); // Kill pin on lin…

You did check the Reprap Wiki page? And also all the links to discussion grouds etc.?http://reprap.org/wiki/Delta The problem with these printers is not the electronics: You can use any existing RADDS, RAMPS, Duet etc. pp. board and it will work ju…

Yeah. I dont think anybody will run more than 10 mm/s filament (~ 24 mm3/s... even with a E3D Volcano that is hard to do), you are right. And even if: Then the PID kicks in again and should deal with the rest.
-
Cool! Glad to see you like the idea! Implementing Kc into the PID loop should then be pretty straight forward, as there are no if/then's to set. If one does not want to use Kc, just set Kc to 0 and it will be plain old PID/Dead time control again. …

Did you check your endstops via "M119"? (http://reprap.org/wiki/G-code#M119:_Get_Endstop_Status) Check whether they report back correctly to Repetier Host (both activated and non activated). Perhaps the configuration for them is not correct (pullup,…
-
I think I understood you now. I was a little bit confused by the last sentence. Yes, after Escher 6-factor, I printed https://www.thingiverse.com/thing:745523 and corrected both the delta diagonal rod length *and* the diagonal rod corrections. The d…

@paul_delta: When Escher calculator is implemented, steps 1 - 4 could be replaced by a Escher 4-factor calibration (it levels the bed and calculates delta radius). The only extra-thing to be programmed then would be step 5. @Repetier: I tried 7-fact…
-
I also *do* have the best results using Escher's calculator - I never said anything else. I do not understand how you interpreted my writing as "inability to use this tool". I have had (by far) the best results with this calculator. I just wanted to…
-
Short update: No luck with that: Changing endstop positions will counteract the angle adjustment. It all gets just worse and worse. I will stick to the plan to level the bed via Escher as far as possible and adapt geomentry via transforms and axisco…
-
Just a remark: For now I will try to use Escher for 4 factors only (endstop positions = bed leveling, delta radius) in conjunction with (#spooky voice#) the thing (#spooky voice off#) you linked earlier. That might work well.
-
Hey Repetier, the thing you linked is exactly the thing I used to try to calibrate my printer after doing Escher's optimization. The problem with this is that the linked thing and Escher are counteracting each other: - Escher tries to adapt for z us…
-
Just a little add-on, as I ran into some problems using Escher's method: Using it, the bed gets levelled VERY nicely indeed, but x/y scaling and angles maybe off by a little. But correcting these via diagonal rod errors and angles will counteract Es…
-
Unfortunately no error message at all. It just went outside bounds (for me to a radius > 80 mm) and tried to measure there. When trying to move to the next position, the stepper lost steps and the whole thing ... well you know what happens next. …
-
Yes, I understand you. Right now, the extrapolated points are (X extrapolated, O measured): XOOOXOOOOOOOOOOOOOOOXOOOX So I assume that the X's are either the average of the two O's next to them or a linear extrapolation. With three X's the thing wou…
-
Yes, I understand. But setting the rectangle to be sufficiently small will inhibit the possibility to distort-correct the complete printable radius. In the worst case one will only be able to distort-correct 0.707 * printable radius of the whole bed…
-
Hey paul, hey repetier, back from the escher / z probe / correction front with good news: I printed out Pauls magnetic z probe mount (http://www.thingiverse.com/thing:1198256) with near-zero x/y offset (for me its in the 1.5 mm range) and re-tested …
-
Yes, I did. I prepared all rods using two M3x50ish screws to align all six rods on both sides via their rod ends. They should be within +/- 0.1 mm range.
-
I dont think the online configuration tool is capable of importing older configuration.h's. If you want to migrate to 0.92.8 you should define your new configuration.h from scratch I believe. Otherwise there will be some mess going on for sure. Mayb…
-
Hey paul! Back from vacation just now. Will retry with manual testing (i.e. paper method) as my FolgerTech Kossel has a HUGE z probe offset in x/y directions. Will report back! My diag rods are nearly perfectly even (margin of error certainly small…

Hey! After some more experimenting I finally came behind the mysterious behaviour of my Delta:The jaggy X/Y movement only happens when movements are issued, which either do not enter the move cache (I assume) or at a to late time. I.e. when I G30 so…
