Sourcing a UM2 frame

[Mazorah 0]

Hi

i am trying to build a UM2 but i seem to be stuck on the frame and base plate, everywhere i look it is about $350 plus shipping.

what i was wondering is if anyone here knows a affordable place to find these parts?

(not even sure if this was the right place to ask)

i am also looking at the wireharness, and trying to figure out what i need, or possibly buy a wire set/kit. i currently have the ulticontroller 1.5.7.

Note that the UMO is just as new as the UM2 and has many upgrades since it first came out.

The best way to get cheap frame is to laser cut it or route it from a material like, diebond, or plastic. Maybe there is a makerspace or fablab near you that you can visit and have the pieces cut. Plus you can customize it with your own name on it or something. Maybe a "minion" version of the UMO.

The 1.5.7 controller doesn't work with PT100 temp sensor so make sure you get a thermocouple instead - 10k to 100k style is best. Also there are 100 different temperature curves for even just the 100k thermocouples so I would get one from the reprap forums so you don't have to make your own version of marlin with your own thermistor table. They cost less than 1€ so why not get one with an existing table.

I like the "Minion" idea :)unfortunately there is no makerspace near where i live. I did not know about the PT100, so i will buy a Thermocouple from reprap(if i can find it). what is the difference between the UM2 and the UMO when it comes to construction? apart from the injection molded parts. can i use the same belt kit? and does anyone know where i could find a laser cut / cnc milled frame kit?

ultiarjan i left a message for minivipers and thank you

gr5 do you have a link to the thermocouple you would buy for yourself?

Actually a thermocouple requries more electronics and can't be measured with the arduino directly so you might want to go with the thermister route - something like the EPCOS mentioned here:

hi again

i moved away from the UM2 to a custom UMO(some minor changes, not sure if they are good or bad) with a full graphics controller and a ada 597 thermocouple. good new is i built the printer, bad news is i may have fried the arduino..... somehow i turned one of the stepper drivers the wrong way, i am using the a4988 ones. it currently has the ulticontroller 1.5.7 pcb and a heated bed.

i do have some questions for the more seasoned people here (yes i am a noob)

has anyone tried this setup and got it working?

has anyone tried using the UM2 injection molded sliders on a UMO?

and something tells me i will be asking more questions....
