Quotethe_digital_dentist I'm not a big fan of the Railcore design. Too many printed parts that extend beyond the frame, making it hard to enclose. The motor mounts look flexible, the pulley mounts don't look very good either. Standing a post with two pulleys up in a piece of printed plastic and putting tension on the belts is likely to cause the plastic to flex and tilt the post.

That's not an Ormerod, They've taken the name, but that's about it. It is not made by RepRapPro, doesn't use a Duet, or indeed any recognisable parts from Ormerod 1 or 2. It's not even using the 3 point bed levelling. (Just 4 point bed bending) To me it looks like a lot of cantilever cartesians being built at that price point. Unimpressed.

Thank you for the pics. It's shaping up nicely there. I never considered white for printer printed parts, but they do look nice (but like a white car, probably wouldn't after a while of operation)by cheeseandham - Ormerod

After a firmware upgrade, if you have any problems the best thing to do is to backup your old config and then got o RepRapFirmware Configuration Tool and generate a new config. bed.g has been deprecated, if you still want to use it then use the old version of the configuration tool If that solves your issues you can always compare your old config and the new one to move over any settings you waby cheeseandham - Ormerod
Quoteveryevil Interesting, not thought of that. Mine is an omerod 2 so using cheap Chinese supply not ATX supply. The PSU is pretty good IME - however I can't back it up with any science. Quoteveryevil I do have a trapezoidal rod for my z axis and I did completely rework my z axis to be behind the linear rod. I thought keeping the rod and screw in line would help with bed level and squarenessby cheeseandham - Ormerod
The trouble is that Z-banding can be caused by a whole host of things (including the possibility that it's more than one in combination), so this is going to be a tricky one. Stay positive and open minded! Here are a few that occur to me to check, but quite honestly it could easily be nothing to do with these. * Check the temp. isn't changing while printing. * Check you are consistently extrby cheeseandham - Ormerod

Quotesinnedwrong I see from the M208 G-code wiki that the example for minima is M208 X-5 Y0..... (i.e with a minus sign) and also that "The axis limits you set are also the positions assumed when an endstop is triggered." Am I correct in assuming that this means that in the example when zeroing X the position for logical X0 is trigger point minus 5mm and all references to X in the gcode would rby cheeseandham - Ormerod
If the Ormerod 1 is similar to the 2 in this matter, there is an upgraded Ormerod z-corner-bracket and z-foot Rock solid and will not delaminate or break! Parts: - will need a tiny bit of work with a drill and a bit of oil to slightly increase the size of one of the holes.by cheeseandham - Ormerod
Very odd. Thoughts: If M305 isn't set, perhaps try setting it to force it to the correct value? Whilst this Duet wasn't made by the current producers, a post on the Duet forums could be an idea. (dc42 was an Ormerod 1 owner back in the day, and is an all-round helpful chap in my experience.

I've been through several of the lower z mount and have the chunky version now in PETG. Spiff, if you're coming back after a while then let me plug my ormerod wiki . Whilst Ormerod 2 focused, a skim may yield something helpful (and feel free to suggest anything decent you come across.) Good hunting!by cheeseandham - Ormerod
Have you updated the firmware, or changed config.g recently? To me the symptoms sound like you've got a 4.7k board , but M305 isn't set to reflect this. Quotelinked webpage If you have a 4.7K board, and don’t make this change, your temperatures will report very high at room temperature on both the hot end and heated bed, and will over-read at the target temperatureby cheeseandham - Ormerod
I like that. I will have to investigate this further and perhaps rebuild using the old acrylic x arm. I'll post once I've tidied up my workshop and done the deedby cheeseandham - Ormerod
Quoteormerod168 Part of that could be pressure from the bowden cable pushing the nozzle down, try a calibration without the cable Erik I didn't mean to derail this thread, so I'll be brief and mention that in this thread you suggested that, and checked that (and a bunch of other things), and unfortunately it's not the bowden.by cheeseandham - Ormerod
I would agree with the acrylic rib, I'm currently unsure about my (unknown source, came with an ebay purchase) aluminium x rib. It's one of the few things left in my mind that could be causing a wave on my Ormerod i.e. I suspect that the cut where the runner is running on, is not perfectly straight. I put it all down for a couple of months recently (due to frustration and a lack of time) I gueby cheeseandham - Ormerod

Wes, I don't know if it'll be handy, I've been thinking of trying this out. Take a look at I like the way it locks to the bearing, and having the runner on the outside again, maybe you'll want to incorporate parts of its design into your redesign.by cheeseandham - Ormerod

spiff, Yes, moves require S2 before homing, so homing files require some minor changes. You can use the Reprap Firmware configurator to generate new files for any firmware, or as I assisted an Ormerod 1 owner recently, this thread (and this particular message) may help, as well as the config bundle I generated for the Ormerod 1 which you can view the homex,y,z,all for yourself and check the chaby cheeseandham - Ormerod

Quotesinnedwrong If so it then raises another question. On my original Ormerod my slicer Slic3r V1.2.9 as per the orinal reprappro config file turns the cooling fan on after 3 layers with the command M106 S255. I see the firmware defaults to fan0 if the fan isn't specified in the M106 code but if I wanted to use a different fan how would I get e.g M106 P1 S255 into the slic3r output?

FYI in case you feel it's useful: "Derived from Treito's design, this is my version. I changed the design as this prevents the IR PCB from colliding directly with the Z Leadscrew, as this could cause a short/damage."by cheeseandham - Ormerod
Quotedc42 That height map shows 3 features: 1. The wave. This suggests that either the height or the angle of the print head varies with X position. 2. Ridges and valleys in the X direction on alternate rows of probe points. This indicates that the height or angle of the print carriage depends a little on whether you approach the point in the +X or -X direction. I have a busy couple of days ahby cheeseandham - Ormerod

Quotedc42 I've seen elsewhere in these forums that those in the know advise against using linear bearings. Linear rails are recommended instead. I entirely agree, and I'm starting to build a CoreXY with linear rails (Based heavily on the Railcore 2 ZLT and it's components, just a few changes). However I'm not good enough with CAD to redesign the Ormerod 2 to work with linear rails Perhaps I'mby cheeseandham - Ormerod
Wes, The pre-load is already pretty high in my estimation. It was a lot more than my previous Ormerod 2 , and I increased the current from 800 to 1000 to assist it moving well. The only play I can find of any kind is that the hotend can move up and down very slightly as the 9mm bearing which to my mind is standard in Ormerods, (I thought one of the advantages of the cantilever cartesian design wby cheeseandham - Ormerod
