On the subject of accidental clicks, it is also rather easy to kick off a print rather than deleting a file. Clearer separation of the controls or a confirm dialog would help.by bobtidey - Ormerod
Thanks for doing this. I particularly wanted to take advantage of the repositioning holes together with the extra depth. I did have a problem with the first print generated from the last version before the lettering was added v6. All seemed to be going well but when I came to remove it, it came off in 2 pieces! The external screw hole bracket was not attached. Looking at the g-code produced froby bobtidey - Ormerod

Looks a bit like this recorderby bobtidey - Ormerod
I have played around with this a bit more to generalise the file upload and have had some success but there is still a file upload problem. This is based on v0.76 web and 59a firmware. I basically just added filename support into the M560 command and added the subfolders js or css at the web end according to extension. This shows the upload area where I added the www item.

Those all sound great. If we can get a fraction done it will step on the web interface a lot. 5) More speed is always worthwhile. Although uploads are much faster than they were at the beginning and are a small proportion of overall print time, they do involve hanging around while they complete. I wonder how feasible it is at the Duet end to support a more standard multi-part/form upload or maybby bobtidey - Ormerod
I don't understand your nut arrangement there. There seems to be 2 nuts together in a 'lock' configuration. Normally there should be one nut, either normal or longer version which is then held tight in the nut trap but as free as possible to rotate on the rod. 2 nuts if they bind together will increase the friction with the rod and lead to greater wear. I could see it working if the lower nut isby bobtidey - Ormerod
Quotedc42 Bob, I agree. The firmware already supports uploading other files, so the work needs to be done in the web interface. Maybe Matt will have time to do this soon, he's better at web/javascript code than I am. I played around with this a bit. The sys side is easy and the current config.sys control does actually allow any gcode file into the sys folder. It passes the filename over in the Mby bobtidey - Ormerod
Thanks for the worthwhile speed improvement. Given that most updates to the web side involve reprap.htm and reprap.js it would be quite nice to update the reprap.js from the web page as well and avoid SD card removal when it just those two.by bobtidey - Ormerod
I think that is essentially the same as Kim Brown's probeless technique as described here . The Ormerod head is not sprung but does have a bit of rotational give and combined with gravity gives the equivalent of a spring. The switch then detects a bit of rotational displacement. Dc42 mentioned he was checking the same idea but with a force sensitive resistor rather than a micro-switch to detectby bobtidey - Ormerod
If you are trying to log on then it sounds like you are trying to use the original web interface supplied by reprap which was very problematic to get going. Once you can see the device over the LAN then you will find it much easier if you use the iamburny web interface in conjunction with dc42 firmware. Reprap have just upgraded to using a version of the iamburny web software but is rather out ofby bobtidey - Ormerod
I think you are looking at the www files as published by reprap. Reprap.htm is their version of a web interface. They have also included a very early version of the iamburny web interface reprap.remote.min.htm. To use the latter version you would rename it to reprap.htm (and removing or renaming the original). To be honest if you want to make changes to the web interface then you should be lookby bobtidey - Ormerod
Thanks for the measurements. As you say there are two areas; the drops in the cables and the PSU itself. The drops in the cables can certainly be improved by thicker cables and more direct wiring. The main issue with ATX supplies is that they are intended to deliver multiple voltage outputs. To keep it simple most designs regulate their output by using a combination of the +5V and +12V outputs fby bobtidey - Ormerod
I think this means the connection is now direct between the PC and the Duet rather than via the router. This probably needs a cross-over ethernet cable as I doubt there is the auto-mdi-x supported. It also needs the version of the web support not requiring internet access either with all files served by the Duet or with a webserver local to the PC.by bobtidey - Ormerod
With the standard Ormerod + ATX there are 4 circuits for the 12V supply (2 in the 4 pin connector and 2 in the multi-way) so the capacity is fine even allowing for less than perfect sharing of the current. When you use just 1 4 way connector then the load on the wire gauge as supplied is definitely excesive and the load on the connector does not leave much safety margin. Apart from overheatingby bobtidey - Ormerod
As you have swapped the PSU I would say you want to abandon the 4 pin connector altogether and wire with at least twice as much conductor area directly into the Duet. If you just increase the wire and retain the 4 pin connector you will still be stressing that type of connector with more current per pin than is comfortable. The pwer distribution pcb is not doing anything of value if you are not uby bobtidey - Ormerod
Even if you are just using +12V supply form the ATX unit then you need the larger multi-way plugged in as well. This has two +12V connections in it as well and multiple grounds. It will spread the load current over more wires and connectors. You could up the gauge of the wiring to something more like the wire used to go into the Duet but if you aren't going to use the multi-way then I'd go direby bobtidey - Ormerod
Reprap support were pretty responsive for me on the two occasions I contacted them; first to get my early Duet with twisted resistors replaced and second to get a quote and order a spare stepper motor. The design concept works well for me, and I did not have any great difficulties getting decent quality prints even with the kit as supplied. I can see that anybody expecting to get a working printby bobtidey - Ormerod
A few minor updates and adding M998/999.by bobtidey - Ormerod
Stand off for the board mounts sounds good, particularly if you make the right hand one separate from the T-bar screw and then offset a hole for that to the left. The idea being to be able to position the enclosure more to the right away from the X axis. Currently the T-bar screw hits the extrusion end stop and limits the positioning quite a bit. The stand off would need to be effectively self taby bobtidey - Ormerod
I had about 2.6mm clearance to x motor so extended it by 2.3mm. It fits with just about a 'paper' clearance! This is just a variable in the scad file and I think a base of 1.8 would still give decent support for the bolt. There are possibilities for more radical re-design, maybe orienting it to favour the printing of the z-trap part vertically to ooptimise the quality around the critical bit.by bobtidey - Ormerod
Quotedc42 Quotebobtidey ... and the RepRap wiki has lots of GCode info but they have stuff that is not in Ormerod and don't have some extra stuff that is. Can you provide details? I' already updated that wiki with extra gcodes and parameters that I added to the firmware. The comment was about both existing cheat sheets and the Wiki. The existing cheat sheet was missing much as it wasn't Ormerodby bobtidey - Ormerod
I have been putting together an Ormerod specific G Code cheat sheet. There was a generic cheat sheet from Chill0r on thingiVerse and the RepRap wiki has lots of GCode info but they have stuff that is not in Ormerod and don't have some extra stuff that is.

Yes. The bits that go transparent are in the original STL. Don't know why that happens. I must admit I use F6 most of the time to get reliable results.by bobtidey - Ormerod
You can import the ormerod stl parts as a whole into OpenSCAD - import("path/ormerodpart.stl"); I do find that some ormerod stls need to be 'repaired' in say netlab first as otherwise Open SCAD doesn't like them. You can't manipulate bits within the part as its just a mesh, but you can add parts on and subtracts bits off. So it is most useful for tweaking around the periphery rather than adjusby bobtidey - Ormerod
I also thought the mounting hole on the nut trap is a bit feeble and does not give much support to the nut and bolt. I imported the existing design STL into OpenSCAD and added on about 2.3mm on the bottom as there is a bit of room between it and the X motor. This then allowed the hole to be redone and a nut trap added. I haven't changed the main nut mount but it would be possible to beef that upby bobtidey - Ormerod
QuoteDavek0974 As a way of measuring position cheaply and to an accuracy of 0.01mm look to the cheap digital vernier calipers found all over the place, I have 5 in the shop myself, they are only about £8! They work capacitively and are very simple but plenty accurate.

Yes. That was added after my build and I didn't add it as mine worked very reliably. It was only when I had a problem I dug in further. I think maybe the averaging is making it a bit more critical as it takes a little bit longer to see the value.by bobtidey - Ormerod
After changing my X Rib over to the Aluminium part I initially had a problem with X homing running into the end stops whereas it had always worked before OK. I traced this to the IR value having changed a little bit although still fairly high (650) and was not quite reaching the threshold for X home to be recognised. The simple fix was a bit of foil on the tab to raise the value and homing was rby bobtidey - Ormerod
Quotedmould 5V could probably be obtained from the standby (always on) 5V that ATX PSU's have available. I think you get that automatically with this mod. The 3 way header onto the Duet is Gnd, PSON, and 5V standby. So when those are connected through to the power board and the ext 5V jumper used then the Duet is powered from the standby. There is an extra benefit in that this is a little cleanby bobtidey - Ormerod
