@zobiepantslol, Thank you. Well you've convinced me to take a look. best regardsby bower-andy - Ormerod
Hi @zombiepantslol, Yes, I am aware of your fork and was looking at it just this morning. I am currently using @dc42's version of the firmware because of the delta 7 factor auto-calibration G32 command that it implements. Correct me if I'm wrong but I don't think your fork has this does it? The other thing I liked about @3D-ES's Makefile was that it was a "one stop shop" and even downloaded aby bower-andy - Ormerod
Hi @3D-ES, After spending two days struggling, and so far failing, to get Eclipse working on the Mac the discovery of your Make script came as a breath of fresh air. Really! Until, of course, I discovered it no longer works with the latest codebase. To me, a Make file seems a much better approach to the problem rather than installing (and then using) the behemoth that is Eclipse not to mention tby bower-andy - Ormerod
Hi @3D-ES, Did you ever get around to fixing your script for the current versions of the firmware (in particular @dc42's). After spending two days struggling, and so far failing, to get Eclipse working on the Mac the discovery of your Make script came as a breath of fresh air. Really! Until, of course, I discovered it no longer works with the latest codebase. To me, a Make file seems a much betby bower-andy - Ormerod
@dc42, Thanks for that extensive tutorial of how to compensate for effector tilt. This seems a reasonable explanation as to why I was seeing the issue with the IR probe (although actually, the 8mm offset was to the measurement point and not the back of the board - yes, I know it is probably too close for comfort). When I get a moment, I'll switch back from the FSRs to the IR probe and try this oby bower-andy - Delta Machines
Quotedc42 I looked into using the second controlled fan connector on the Duet 0.8.5 as a thermally-activated hot end fan, however I didn't implement it because of safety concerns. It is very important that after a reset, the fan turns on... @dc42, thanks for taking a look at this. I see why the HE fan needs to come on at reset to prevent blocking in the hot end but I don't really understand theby bower-andy - Ormerod
@dc42, that would be really cool. Thanks. best regardsby bower-andy - Ormerod
@Koenig, Sorry, my bad. Yes, you're right the command is really: G31 X0 Y0 Z0.7 P500 I'm pretty sure I was using this at the time, I just retyped the wrong line from config.g when preparing the above message. It's interesting, though, that the 7 factor calibrate works well for me when the probe is central but not otherwise. best regardsby bower-andy - Delta Machines
@dc42, I have been using your mini IR sensor board with the n-factor auto-calibration and I'm seeing some strange effects which I'm starting to think are due to the offset of the probe location from the nozzle centre. As I think you have suggested, I have set the probe X, Y offsets to zero: M558 P1 X0 Y0 Z0.7 even though the actual Y offset is about 8mm. Now, when I do a 4 factor calibrationby bower-andy - Delta Machines
@Darathy, but that board is for the Ormerod only, I think. I am using @dc42's mini IR sensor but this doesn't have the fan control. Anyway, as I said, with the release of the new Duet 0.8.5 with extra fan pins maybe the time is ripe to revisit implementing this within the RepRap firmware itself? best regardsby bower-andy - Ormerod
@dc42, did you ever get anywhere with this idea? Although not using an Ormerod, I'd really like to use one of the new fan pins on the Duet 0.8.5 as a temperature controlled auto fan. In the Marlin world this was pretty easy to set up in the firmware and I used it successfully with a Rambo board to turn the hot end fan on at any temperature above 35C. I think a hardware board is rather an overkillby bower-andy - Ormerod
@Treito, the PSU is the "official" RPi 2A unit. Although I do have a WiFi adapter and camera connected too, I would have thought that the RPi would have enough additional power to run the Duet (I have even disconnected the panel). However, thanks to @dc42, I see that there is a known issue with RPi USB power (although I'm still a bit surprised since I have nothing else connected). I'll try cuttiby bower-andy - Ormerod
Hi, Is this the best forum to talk about general Duet issues, or is there a better place? So, I'm building a delta printer and have decided to switch to Duet 0.85 electronics from Think3DPrint3D (mainly to get dc42's auto calibration). I am powering the board off a single 12V supply, so using the onboard regulator for the 5V electronics. However, I want to connect the printer to an RPi (to useby bower-andy - Ormerod
Hi @AndrewBCN, Did you make any progress with porting @dc42's algorithm to Marlin? Do you need any help; I might be able to find some time in the near future. I have a modified 3DR Simple delta that now includes dc42's IR probe sensor. Previously, I was using FSRs under the bed (with the heated bed supported on silicone pads) and used JohnSL's FSR endstop controller board. I used RichC's mainby bower-andy - General
Quotepugzor The biggest problem was that at some point unbeknownst to me, I'd set the Z probe offset to being 0.8mm. That meant that although the paper calibration worked it was 0.8mm off in the centre. So stupid. It now prints though! A few questions... - After I do the fine tuning calibrations, where's the best place to ask about improving my print settings? I noticed they're a bit messy so Iby bower-andy - Delta Machines
Hey David, This is an interesting question. I come to the Cherry Pi and this forum with exactly same dilemma except that it stems from an attempted build of a RichRap 3DR Delta and the comparison of the prints with a Prusa i3 Hephestos. The prints from the Prusa are excellent despite the fact that the machine itself is a goddamn eyesore. I few months back, my son Harry and I started building a 3by bower-andy - Delta Machines
Hi Andy. I don't seem to have that bag. I have everything in the original box but have thrown some of the bubble wrap away. If you can't find it on your bench then it may have got stuck to the wrap and followed it into the trash. I'm happy to reimburse you if you think it was actually sent. Another Q.The sleeved many core wire .. what is that for? Best regardsby bower-andy - Delta Machines
Gary, Thanks, I don't seem to have that coil of wire. One more question - when fitting the toothed pulleys onto the motors do the screws go nearest the motor body or furthest away. I see that the Mini Kossel instructions from Think3DPrint3D show them furthest away. Best regards Andy Bowerby bower-andy - Delta Machines
Hi Andy, On p17 (http://forums.reprap.org/read.php?178,361141,page=17) gowen shows some small bent wires used to attach the springs to the guides. Are these meant to be part of the kit (I can't find them) or can I just use a bent paperclip or similar? Best regards Andy Bowerby bower-andy - Delta Machines
Andy, Great, that's just what I need, thanks! Should I have known about that diagram? Is there a site somewhere with more information like that or is it just this forum thread? Best regardsby bower-andy - Delta Machines
Folks, I've recently started a CPi III build from a kit supplied by Andy and I'm following along with the pictorial build from gowen starting on page 17 of this thread. However, I've stumbled at the first hurdle (well perhaps the third) in trying to work out how many T-Nuts need to be installed in the top and bottom of the frame.
