It have Arrived. Checked so all parts was ok and there. Looks good so far. With three kids at home i have to leave it for later. Thanx to you guys i at least know where to start and i will change some of the parts at once.
If you shorted it and it says max temp that is normal as wires have almost no resistance and a thermistor decreases in resistance as temperature rises.
if your wire or thermistor is broken it should say “min temp” and refuse to heat.
Also as previously said, X is left to right, Y is back to front and Z is up and down.
The board should have names for the connectors on its back, mine did.
If you’re all set then put some grease on all the bearings, tension it and get started with moving all the axis individually. Then home, test heating and try your first print
Something is still wrong. In the upper left of the display it says its getting hotter when i preheat the nozzle is that right or should that be the heatbed? The other side (right) is still 0. I dont get errors when i move the heatbed therm checker to the wrong place… But i cant heat the board either way.
Hmm… are you preheating from a preset? From your computer or from the LCD menu try heating bed to 70°C.
In LCD menu that is in the menu, setup/prepare (I don’t remember the name properly, sorry) then preheat ABS or PLA then go to the main menu again and scroll down to control (I think it is, again, my printer isn’t with me right now!) and in it you should see nozzle and bed temp. Change those to nozzle = 0 and bed = 70.
your printer may have a preheat option for the bed only, in which case you can forego the second step.
If your bed doesn’t heat up carefully check the nozzle. If the nozzle is also cool then it may be a wiring issue for the bed.
Im trying now. Heatbed is still cold. Maybe its the wrong connection on the heatbed? The wirediagram say is this one but i will try to set the heatbed on on nozzle two and test since it ony not gives me faultcodes when the bed is connected to the right place. I mean i put the temp wires on the wrong place and than it reads ok. Strange but who knows
It’s worth noting that the 3 sensor inputs and 3 heater controller outputs are mapped in the software so in theory could be different between different builds/variants.
Best to confirm the sensors are correct resistance, wires ok and start from there. You can also buzz the heater wires for good connection, not sure what resistance they should have - probably pretty low.
Putting a volt meter on the heater output when preheating will also tell you if the heater is being supplied any voltage. This is a PWM output so the value will vary but again your really looking for something or nothing.
Apologies, if I’m telling my granny how to such eggs on the electronics.
Next issue Downloaded drivers and repetier 1.6.2 and manually tried everything. The z axel only moves on one side. If i take it out of the motherboard the other one can move. Any ideas? Thx
Make sure the both Z motor cable has the same orientation in the motherboard (same order of cable colors also), if the 2 motors don’t work together,it means the motor driver doesn’t have enough power for the 2 motors adjust the small potentiometer to give it more current:
