Me too, please. Ken.by KenF - Ormerod
Thanks Dave. I'll try those tweaks this evening. While you're thinking about the G32 command, and if it wouldn't be too much trouble, would it be be possible to let us add an argument to the G32 command so we can specify the height at which the head travels from one BPC point to the next. At the moment it's fixed at 8 mm absolute, I think. It would suit me far better, and save time, if it was sayby KenF - Ormerod
Thanks, Dave. I'll look forward to hearing from you. Must say, I don't know how you find all the time to do what you do on this forum.Very much appreciated by me and, I'm sure, by everybody else on here. UPDATE 2: Instead of calling M98 Pstart.g in my testspot file, if I put the code of start.g in the testspot file, then all seems to work fine. I.e this works: in combination with the previousby KenF - Ormerod
UPDATE. I downgraded back to 0.78e-dc42 and removed the fifth BPC point from the config.g file, but still had the same problems with homeall.g and start.g. Very odd. Then, realising a common link was that the problem commands were the last commands in the file, I added G4 P1000 to the ends of homeall.g and start.g . That solved the problem, using 0.78e-dc42. I then re-upgraded to 0.78e-dc42 0.by KenF - Ormerod
Everything was working well with 0.78e-dc42, but I upgraded to 0.78f-dc42 last night and changed to five bed plane compensation (BPC) probe points near the four corners and in the centre, and now my Z homing and BPC has gone up the creek. Relevant files attached. When performing homeall.g as part of the testspot file, its omits to do the final line (G30 - z homing). I putby KenF - Ormerod
Thanks very much for your last two postings, David. Very kind of you to offer to sort it out for me, but as I said before, it's not a problem. All my print files have a 'beginning' routine that switches on the fan, and an 'end' routine that switches off the hot-end heater, and then switches off the fan a minute later. I did, however, try the suggestion in your second posting. I didn't have a 5M6by KenF - Ormerod
A lot of the stuff I'm going to be printing is small and could do with a bit more detail than the 0.5 mm nozzle can provide, so I've ordered up a 0.3 mm nozzle from RRP. I realise that I'll need to change the nozzle diameter in Slic3r to 0.3 mm, but will I need to do anything with the layer height, or any of the other settings? Ken.by KenF - Ormerod
Mine arrived last Saturday. Fitted it straightaway. Brilliant! Well done, Dave, and thank you very much. The one thing that doesn't seem to work as it should is the thermostatic fan control. With 12V applied, the fan is on all the time, whatever the temperature. But I do have one of those dodgy Duet boards with the temperature ADC that wasn't set up right, and my workaround has been to put a 150by KenF - Ormerod
There may be a different reason for what's happening with yours, 3djim, but I've noticed similar effects if I connect to the Duet with a browser window when there's already another browser window connected to it. Ken.by KenF - Ormerod
I had the same problem, IBDunne, due to a problem with the Duet board's analogue/digital converter being on the limits of what it can cope with at low temperatures. RRP offered to exchange the Duet, but because of the reported problems with later Duets burning out for a reason they hadn't got to grips with, I decided not to jump from frying pan into fire. Instead I solved the problem based on a sby KenF - Ormerod
Thanks, Dave, but perhaps a bit of a misunderstanding. After I've initially used the switch to set Z=0 at my X,Y homing position, I don't then want to reset Z. Instead, I'd like to be able to move to other X,Y positions and see at what Z positions the Z switch switches there, so that I can check whether the bed is level, and adjust if necessary. Ken.by KenF - Ormerod
PS. Here's a pic of my Z switch ... contact (or not) between the anti-tilt bearing and my alloy arm, with a light spring that rubs on the outer race of the bearing so that the current doesn't need to flow through the balls and lubricant in the bearing. 30 ohms or less when closed. Of course, the nozzle does need to be snot-free at its tip, but hot snot does get squished out of the way pretty wellby KenF - Ormerod
Quotedc42 ... Changes in firmware 0.59b since 0.59a: * The M208 command can now set the lower limit of axis travel as well as the upper limit. For example, you can set the X-axis lower limit to e.g. -10 so that X=0 is at the edge of the bed. Add parameter S1 to set the lower limit, otherwise the upper limit it set. If you set an X-axis lower limit, then this will be the value set when the endstoby KenF - Ormerod
I've tried that. Hope I got it right, but all I have to edit the reprap.js file is Notepad. Think we're getting there, but not quite all the way. I uploaded the modified reprap.js using the upload www facility. Then I uploaded a modified homex.g file using the upload sys facility and ran it. Still performed the unmodified action. Uploaded modified homex.g again, and that time it did what it shouby KenF - Ormerod
Quotedc42 I found the problem... Ah, we crossed. I'll give it a try. Thanks Dave.by KenF - Ormerod
Quotedc42... What I'm finding is that the first time I upload config.g in a new instance of the web interface, it reports success but the file hasn't been updated. Subsequent attempts work OK. Is this what you find too? ... I've just tried this with a different SD card (in case there was a problem with the first one): Delete all files in SD sys directory, and install SD in Duet.

I've installed the latest firmware and web interface, Dave, and it's getting slicker all the time. Well done! However, I have had a problem uploading/updating files to/in the sys directory of the SD card. Out of umpteen attempts, it's only worked once. After updating just one file, taking the SD card out and putting it in my computer to see what's happened, more often than not the original fileby KenF - Ormerod
Quoteormerod168 ... No, it rolls inside the bearings inner ring and that's the problem, ... Ah, so the inner race of the bearing is not being prevented from turning on the bolt by a nut on the end of the bolt? I found with mine that first I needed to tighten the hobbed wheel on the bolt, and then the nyloc end nut on the bolt, both far more is probably good for them in order to stop things slippby KenF - Ormerod

QuotedmouldSurely if you reverse the direction of one of the motors but not the other, your prints are going to come out as mirror images? Indeed, Dave, they will. But I've also swapped the X and Y motor connections to the Duet, and that on its own also makes them come out as mirror images. The two mirror images combined result in no mirror image, but a rotation of 90 degrees and a translationby KenF - Ormerod
QuotePointy Quotedc42 I've just implemented a change to M208 to allow the user to set lower limits as well as upper limits. Will be released in 0.59b. Man you are efficient! I was going to ask about this in the firmware thread, but you are just too quick! Regards, Les I'll second that. Thanks very much Dave!by KenF - Ormerod
Quotejstck ... or you can just disable all the range checking altogether with "M564 S0". That means you can run outside of the travel range of the printer, having motors or belts skip and make noise. I have had that happen quite a lot though, and it has never lead to anything actually breaking (even though it sounds like it). Ah, thanks very much Jstck. I hadn't noticed the M564 command before.by KenF - Ormerod
Hi folks. I'm new on here ... one of those who bought an Ormerod kit from RS without doing much research, and was, how shall we say, 'surprised' by what I got. Having redesigned most of it, I've now got something that works. Anyway, that's a long story. One thing I found confusing was the arrangement of the X and Y axes of the thing. I normally sit with the end of one of the Ormerod legs nearestby KenF - Ormerod
