its 37 in my room and the printer is melting

frustrated.. Today Its 38 degrees in my room and I have just finished printing an ABS bowden drive plate, and the x motor mount is like rubber, drooping. I haven't been able to print that part yet. I have had to make aluminium plates for all the important parts. The Y axis motor twisted badly, the b...

Re: New hotend peek melted

yes mine did too. i set if for 275C to get ABS to flow and checked with thermocouple . the tip was at 245 and it melted. Ohh the grey ABS did start to flow then.. The blue I have now runs at 220C

I am thinking of making a spacer from bakerlite/canvasboard.. or from a roller from a laser printer..

Re: mounting the display unit

I only use ABS so i need a bed at 100-110C. I have insulated the underside with 8mm thick double corrugated cardboard. With the original mounting 8mm was all I could fit. Now with the 20mm clearance I could add a layer of 6-8mm ploystyrene (packing). I also add a sheet of cardboard to the top when h...

Re: mounting the display unit

it only arrived on monday.. straight from Netherlands. Posted 19 Nov.. i will print one. No problems with that. But lots of problems with ABS and heat. The bed is heated to 110C and the radiated heat rises and makes the extruder motor so hot after 30 minutes, it burns.. And the heat flows to the knu...

Re: mounting the display unit

nope. not there. No info on how to attach the display to the rails so it wont just fall off. the cables are connected on.. but they push the box off the rails. as i said the only way I can make it stay on is Blu-tac.. why didnt the box come with moulded clips to snap on the rail? https://dl.dropboxu...

mounting the display unit

ok, i give up. I cant find anywhere how to mount the ldc display box to the frame? am I missing something.
took 8 weeks to get the display.. guess there were supply back orders..
thanks

Re: Switching Vanes/Opto-Sensor

and they got the VCC voltage wrong too. The Opto VCC is powered from 12V through a resistor. Totally stuffs the photo transistor output. Take all 3 opto VCC wires and connect to the power supply 5V terminal. Then all the leds will work correctly and you will get clean switching. IF you got a red uni...

Re: Opto-sensor does not work!

if you have a felix 2.0 with control board 2.1 you need to take the opto VCC lines and wire to the power supply +5V. and if you have a RED felix you will have to use tipex on the vanes because the IR beam goes straight through the red abs.. as soon as you can print some black or grey replacement par...

ABS printing and non-stick to heat bed. Optos

I built the machine this weekend. Took me 12 hours. Problems with the optos. They are wired wrong in the instruction Manual and the 2.1 PCB has VCC connect to 12V through 1K resistors. This doesn't work. Rewire the VCC wires to the 5V from the power supply. The home function didn't work. Needed the ...

Re: Opto sensor issue??

yes the opto sensor connectors on the 2.1 PCB, the VCC is 12V through a 1K resistor. It doesnt work because the photo transistor is biased from the VCC line with a 10K resistor.. When the transistor is off the SIG wire is nearly 6V, not good for the micro. The fix is to connect all the opto VCC wire...
