Look at the traces on the motherboard. If there is a resistor connected to the trace, it's low, otherwise it's high. If it's hardcoded in the software, then calculate by distance moved.by etfrench - General

Fortunately, it isn't inside my house In any case the amount used is .4kg in a 400m3 shop. It's nice to know the toxicity, but given the volume of PIR and the volume of the shop, I don't think I'll worry about it too much. p.s. The nylon and ABS filaments will probably give off more toxic fumes than the insulation and are much more likely to actually start burning in a 3d printer fire.by etfrench - Reprappers

Much appreciated though. Why? They are more than adequate for the loads a printer will be putting on them. I thought they would wear out very quickly and wouldn't be very precise. I could be wrong.

What do you need a computer for other than downloading stl files and slicing them? The only reason my delta is ever connected to a computer is to update the config file.by etfrench - Delta Machines
Dimensions are quite close to my delta. Here are my recommendations: There isn't any need to cut the bed down and you can always make the arms longer if you need to make a larger print. The 300mm heat pad will work fine. Angle the balls on the carriages so the arms can go to 90 degrees with no interference. My arm length is 376mm with an arm radius of 196mm.

I used rigid insulation on two sides of my delta. I'm still working on the design for the third side as I want the extruder outside the enclosure. Currently I'm just using a piece of plastic bag to cover the front. The temperature several inches above the print bed stays around 40C. I expect eliminating drafts is more beneficial than the temperature.by etfrench - Reprappers

First step would be to verify the gCode is correct. Walk through the code to see if the drop is there. You can search using "Z" to find each change in height.by etfrench - Reprappers
Quotethe_digital_dentist Lapping the threaded rods makes them look pretty up close, but it doesn't straighten the rod which is the main problem with using threaded rods instead of lead screws. It's like my grandmother in Tennessee used to say: "you can't make a silk purse out of a sow's ear". Threaded rods are the sow's ears of 3D printing. Not only does it make them pretty, but it decreases sby etfrench - General
Leadscrews can have any thread form, so your M5, 6, or 8 threaded rods will properly be called leadscrews. A leadscrew should not be expected to add any rigidity to a frame. A larger diameter leadscrew will have less whipping at higher rpms and less droop over a long expanse. I don't think it's possible for anyone to tell you what diameter leadscrew you need without knowing more specifics abouby etfrench - General
Since you only need this for one generation of bees, you could probably drop the food safe requirement. ABS can be smoothed with acetone to get really smooth surfaces. Baking it (or PLA) for a few hours at a temperature near the glass transition state may remove most of the volatile substances in the plastic. You could also use shellac to seal the plastic which would give you a smooth surface aby etfrench - General
The only real issue I've seen with the cooling block above the effector is there is less room for fans. I modified a E3d clone similar to what you did for my first effector. I've since switched to a Prometheus hot end. Here's a small video printing nylon trimmer line:by etfrench - Delta Machines
The easy answer is you can't make a prusa i3 print to those tolerances unless you have an unlimited budget. The better answer is you need to change to a print technology that will print to those tolerances. SLS would be one such technology.by etfrench - Reprappers

Quoteo_lampe The bed is now fully insulated underneath, which is another benefit. I have an 5mm thick aluminum bed with 350mm diameter and it takes only 15min. to heat it up to 110°C. I'd rephrase that to say 'it takes an agonizingly long 15min. to heat up to 110°C' My 8mm thick >400mm diameter bed (325 printable) takes about 5 minutes to go from <20°C to >120°C.

Simply adding a spring loaded tensioner for each tower between the effector and carriages will give you any amount of holding force to weight ratio desired. @Andreas15: Consider adding a mounting point for these on the effector and carriages.by etfrench - Delta Machines
