can I desolder the driver and solder a new one on?

Hi
the v+ and v- of the fan shorted out for a split second
the motor was work right before hand
the motor only spin in one direction (anti-clock-ways) with both commands
try connecting a different motor, same results
motor sounds the same before problem
cheers

z motor only spin one way after one of the fan shorted out i checked y,x they seem to work ok,
any help would be nice
cheers

I guess I can after I get everything up and going

@deckingman:

Wow that's impressive. May I ask how the hot end is fixed to the carriage after it gets picked up?

magnetics, holds real well

build area is X720 Y320 Z 800
With 3 hot ends, changible tools
diamond hot end
e3d volcano
direct drive with e3d hot end
so the hot ends get pick up as need in the print then droped off

I call it "Small Box"

hi
thank for the help
moving from front to back from left to right to jurks in both directions
moving front to back right to left to moves smoothly in both directions
I have nema 17 0.9 1.7a motors running at 1.3a in software
cheers

I have built a corexy, when it travel just in x or y it travel just fine but when it moves in a diagonal it jurks an lose step or some thing (it doesnt travel to when it ment to)

any one have any idea

@dc42:

The firmware already does some filtering.

What is a rex_c100 ?

rex-c100 is a Digital PID Temperature Controller

@dc42:

Themocouples only output about 40 microvolts per degC, so the wiring between the thermocouple and the daughter board picks up interference easily, especially by induction. Use twisted pair wiring all the way back to daughter board, and keep it away from other wiring as far as possible. If you are using a bare tip thermocouple, make sure that the thermocouple tip is insulated from the printer metalwork. If you are using a cartridge thermocouple, grounding the cartridge housing may help.

Is there on way to filter the noise (2000c) out by firmware so that it ignores the 2000c reading

I tryed to strip some coax cable but the sheild wire keeped coming with it then i tryed just earthing the sheild thats already on the thermocoupling and that just gave a reading of 2000c then I connected it to a rex_c100 and that read the thermocoupling with out no nosie

Its a cartidge thermocoupling ill try earthing the heated bed to see that makes a difference
It insulated wire within a braded metal outer
The bed has a AC heating pad on witch I havent been able to try yet beause of this issue

Hi
I have a duet wifi with a thermocouple in my heated bed it keep jumping up to 2000c even when only the 5v power supply is going so I was wondering if there was a filter in the temp so it did not register just the 2000c would that work?

hey just quick question I have mesh bed leveling set up how do you in crease the movement travel speed ( y & x ) as it take about half an hour to level my bed and the head moves so slow while leveling
cheers
