Printing issues ...
Detecting glass build surfaces is notoriously difficult for IR sensors and they get reflections ftom the top and bottom surface of the glass sheet that creates a significant error.
If you really wanted an alternative build surface then a commercial build surface that is not transparent and has a matt surface finish would work best.
Edit: I was asking about you abs because I wanted to understand

At the moment your bed compensation or level check is likely to be incorrect. As cheeseandham pointed out your trigger value is much lower than the sweet spot for the sensor that it's designers have indicated. This will mean the the system will attempt to find your trigger value but the level at which it does will be inconsistent and have large error. I'd say get the system working as standard a

Auto ignition temperature of paper would appear to be over 200C
I've moved to using spray bed adhesive called 3DLac, which seems not much more than hairspray. Because I moved away form the Kapton tape I couldn't use plain paper. I now use printer envelope labels trimmed to 25mm square, but only run my bed at 60C for PLA.

Are you running the standard RepRap heated bed? If so I'd prepare it as per the instructions. Here's the build surface prep instructions for the Ormerod2:

Are you lowering the IR sensor over one of the paper targets on the upper surface of the glass plate?

I've currently only got PLA running on my printers but plan to enclose them and move onto PETG soon. Once that is done I may consider creating an update bundle to include the parts needed to convert an existing Ormerod into one of the tweaked versions. To be honest though I doubt there'd be enough interest in it.

Morning all,
Updates on my project are scattered over a few threads so I thought I'd condense and summerise here.
I kicked off this goal mainly as an exercise in FreeCAD and in order to adapt a few of the parts in order to reduce the failure rate of the PLA components. I appreciate some people have already done many of these mods and I am re-inventing the wheel in many places but what the heck!

No problem. I was worried it was going to blow the hotend into an error state but it seems to cope. The temperature drops when the fan enables, but it corrects before going much outside 5C from set point.

The cooler is a 50mm radial mounted to the stock fan mount with a custom duct/mount. I'll share the CAD later today.
Edit:
I put some heat reflective tape on the faces nearest the hot end and heat sink vent.

Current implementation uses a 50mm radial and drilling out the standard acrylic mount a little. Not that directed though.

Yes, considering the Ormerod extruder had no pressure adjustment iy seemed fire and forget. The only issues I've had have been the bowden clip wobbling reduding retract effectiveness and standard PLA being a bit crap long term and cracking up and letting go.

With regards the original post I've tried the standard ormerod and mendel extruders, E3D titan, and Bondtech.the printed extruders worked well but didn't last well. I never got along with the Titan. Found it fiddly to set up, lacked power and ground filament when there were loads of retracts. That said it was consistant once setup. The bondtech is my favourite but I don't think it is the only do

Ok, from what I can see in order to do probing completely manually then you need the following lines in your config file:
M558 P0 H5.0 F120 T3000
The critical parts of this are H which defines the height that the probe should be above it's trigger value before it displays the pop up to drop the nozzle to zero. F usually defines the speed that the head dives when it is auto-probing. I'm guessing

I'll have a dig around tonight. I think it is just a case of defining tue probe as manual, defining a grid, and then calling something like G29 or G32 to kick it off.

Benchies succesful at 0.2 and 0.3mm followed by a Hellboy head! Happy as. I'll update this with tje settings I used when I get a chance. Potential for speeding up the 0.2mm builds but 0.3 where at the point where I get extruder drive issues on a calibration extrusion into free space, so not pushing any further with speeds on that!

Hi all,
I'm interested in comparing settings. I've been having a right fight with the benchy and specifically the bow and rear corners. All tend to curl up. I had thought this was purely a cooling issue but when I tried faster processing settings the curl became much worse. So here are my critical config settings and the Slic3r settings:

Have you tried to adjust the twist of the y axis rods at all? On the recent firmware that problem looks like a twisted bed.

Trouble is guided contact relays aren't cheap and the whole interlock system cost more than some cheap machines. It's on my todo lost to see how economically I could make this.
...additional interlock devices should be easy enough to add in between the coils and the e-stop switch. Testing needs to be carried out to ensure all devices in the chain work as expected rather than left alone for momth

Safety & Best Practices
With my last build I made a serious stab at a reliable interlock that mainly focused on the heaters and steppers. This was on a duet, both 0.6 and second generation, specifically an Ethernet model.
Heaters are switched ground, so could be powered by a seperate power supply that I interlocked on the mains side. The duet has the option of powering with a 5V supply for the controller and VIN for s

Got plenty now thanks until I'm in a position to get a Delta or Core XY. The one I just bought was £80 with a possible dead control card but the extras I was planning to get long term. A steal I thought.
Thought you only just got it going? Sorry to see you getting shot of it if it is yours.

There is also a config-override but at the moment that just includes the PID values from the hotend and heated bed autotune.

Glutton for punishment! Just bought a second hand unit from EBay from Fleet area with Aluminium bed and x-arm but potentially dead duet. Currently building up a kit of tweaked parts in order to resurect bits of an old ormerod. These bots will save me some wiring and save me rebuilding at a later date with the aluminium bits.

No worries, found it:
On the Duet 0.6 and 0.85 the default bed thermistor resistance at 25C is now 100K (as it is for the Duet WiFi). If you have an Ormerod, Huxley Duo or RepRapPro Mendel printer with a 10K bed thermistor, you will need to add parameter T10000 to the M305 P0 command in config.g if you don't have that already.
