Hi everyone! It's been a while! Does anybody have a modified version of the lower-z mount? (this one here: ) That part that wraps the steel bar is really thin, and seems to be the weakest point of the entire part. I've now managed to snap two lower mounts now in the exact same place!by 0x0000 - Ormerod
QuoteTreito You are talking from the y-axis. The x-axis has no acrylic parts with a hole where the belt is running through. The x-axis moves the head. However my OM2 uses a GT2 belt without any problems (16T pulley). I mean this bit here. My GT2 pulley barely fits through the hole:by 0x0000 - Ormerod
I have a similar problem running GT2 pulleys/belts on my X-axis. The hole that the pulley fits through has barely enough clearance to fit the GT2, and if not carefully fit it will rub against the lasercut part. I recently swapped mine for an aluminium version which made the problem worse. Liberal amounts of lubricant has solved it for now, but I'll probably need to file it out a bit to get it toby 0x0000 - Ormerod
Yes - check tag "528.4" on Github: I believe 528.5 contains minor revisions but was not organised completely before RepRapPro closed down.by 0x0000 - Ormerod
QuoteSardi Thermistor - I messed up the connector on the thermistor on the day I assembled the kit. The wires are so light and tiny, and I ended just connecting wires directly one to another. Also, cant find the right thermistor in my country (Thermistor, NTC, 10 kohm, B57863S Series, 3988 K), will any other 10k thermistor work? I found others with marks 3435, 3950 etc..

Thanks for this! So there's just a hole drilled through the "hump" on the x-rib? How large is the hole? Is it threaded or just drilled straight through?by 0x0000 - Ormerod
I'm doing some repairs on my z-axis at the moment, and my M5 threaded rod keeps popping off of the bearing on the corner of the Z stepper motor. The threaded rod isn't straight anymore after 1 year of driving the printer, and I suspect friction at the z-nut-trap is greater than the friction keeping the gear on the bearing. Rather than use the same threaded rod, I thought I'd explore other optionsby 0x0000 - Ormerod

Quotebrlowe Hi all, I know I must be the slowest builder of one of the printers ever. Definitely not the slowest - I'm still building mine after 15 months. I was held up life adventures, then an uneven desk, then twisted Y-axis rods! I've finally found some time to sort out my printer's issues with some metal replacement partsby 0x0000 - Ormerod
I had this problem when I wasn't able to find brass unions anywhere. You can carefully thread an M4 nut onto the PTFE tube. Do that for about 10mm or so, then unscrew the nut. Pop the nut into the tongue slot, then thread the tube back onto the nut while it's in the hole. It can be a bit finicky, so use a flat screwdriver to hold the nut in place while you thread it on. I wrote a post on it here:by 0x0000 - Ormerod

PTFE fumes need to be handled with caution. I had a guest fry something in a Teflon pan once, and we had to evacuate the house for a couple of hours. The smoke is lethal to birds and it'll give you nausea with a raging headache for the rest of the night. Certainly not a medical emergency but it's also not pleasant. My understanding is that PTFE begins to decompose at 260C, but I've read many difby 0x0000 - Ormerod
They do turn, there's no skipping that I can see. The current theory is that my print speed is equivalent to extrusion speed, and 80 mm/s is too high.by 0x0000 - Ormerod
Somewhat related, I'm using Cura to do my slicing, and it suggests a print speed of 150 mm/s for a "well-adjusted Ultimaker". Is this the speed at which the extruder spits out filament? What is the optimal speed for the Ormerod 2? While I'm proud of my home-built Ormerod, it's certainly not a well-adjusted Ultimaker... my stock extruder jams at 40 mm/s!by 0x0000 - Ormerod
No luck yet @PeterSimpson! I managed to get my bed reasonably level and figure out "Z-home"... I managed to print the perimeter of the Z-trap, but I can't seem to extrude beyond that... it makes all the motions but the hotend stops extruding after a couple laps around the part. I'm thinking that maybe my nozzle is clogged, or there's something amiss with my extruder.by 0x0000 - Ormerod
I believe the firmware will stop extruding once the temperature hits 160 to prevent damage to the hotend. Since 170 is quite close to that, maybe it's briefly dipping below the cutoff temperature? This can be overridden by enabling "cold" extrusions with the M302 command, though that's usually only done during maintenance.by 0x0000 - Ormerod
I'm keen to try but my printer still needs quite a bit of work! If I get it going this weekend I'll DM youby 0x0000 - Ormerod

Which parts need to be redesigned? I found this one from Joar107 that looks interesting. No need for a y+brace, the clamps look like they screw directly into the bed: I'm having a closer look at the alternative aluminium parts with an eye for hand cutting them. I think some parts on the XPlate in particular can be eliminated to make cutting simpler (for example, the ridges above the motor and tby 0x0000 - Ormerod

QuoteSolomon262 Interesting, I have got two pice of 2020 aluminium from Miter 10 in Blenheim during 2007. Although they aren't for building 3d printer and I have to spend half day to tidy up their rough cut. Anyway they are always changing their catalog, I won't be too surprised if they are not doing it anymore.

Has anyone managed to fit DaveK's / DC42s aluminium bed to the Ormerod 2? I have a 5mm aluminium plate, just wondering if its worth the trouble cutting the shape out. Thanks!by 0x0000 - Ormerod
Definitely not any 2020 or 2040 aluminium at Mitre10 (or Bunnings). I've contacted several aluminium extrusion companies in New Zealand, and neither they nor their suppliers carry it. Ullrich suggested that they're probably proprietary dies, and not produced in NZ CNCKits.co.nz is the only NZ based supplier that I've found for 2020 and 2040. They're based in Auckland.

Hey there, I built my 3D printer almost entirely from NZ based parts. There are some things you won't be able to find at all in New Zealand.

What is the purpose of the "large gear" and "small gear" DXF files found in the Ormerod repo? These ones: They look a bit like the extruder gears, but after loading them in InkScape I can't see how they'd fit onto the motor. Are they suitable for use with 5mm aluminium?

Is the hotend thermistor connected to the Duet? Check that both wires are seated correctly in the connectors. Could be that your thermistor is faulty. Has it ever worked?by 0x0000 - Ormerod
