put the right config... h file for your printer into the marlin directory before flashing

and enjoy

good work vert

seems to be normal that the a10 die after some month

stupid me i have ordered an A20 for replacement of my defect A10
but that can go wrong too

@ William can you give me a link or contact for the sales support? my thermistor cables from bed are placed in the middle of the soldered connectors i have problem at two places there is a wrong temp reading at both thermistors shown on lcd both around 125 degree Celsius i checked thermistor both ar...

in this case, if we have same problems with several boards it must be a trivial problem i checked my sensors and all sensors are good after flashing latest firmware i have also set the sensor in the code (configuration.h file) search for sensor type 3950 and in the code you will find the subscriptio...

i have same problem with mine a10 printer, several replacement boards do not work (temperature failure) i spent more money for replacement parts the last month as i paid for whole printer when it comes new @william is it possible to work with adapters or is there any kind of upgrade kit REV B board ...

Hi Stefan, next days i get an A20 with rev3 Board, i am also interested whre to find the right connections. Did you find a jumper or so? Otherwise try the Marlin 2.0.xx firmware from Vertabreaker here in Forum. You can do most settings by this firmware on lcd. As i remind from my older A10 and Rev B...

btw the Rev B board seems to be a bad thing, a wide variety from good and working till broken i compared my pre installed gt2650 Rev B with the current replacement board bot have difference, where through hole vias are filled with solder tin or not or if board ist cleaned up with alcohol or another ...

i found the mistake I have shortings over my pullup resistor system for Heat Sensors. measuring form sensors connecting pins onboard R4 and R58 give wrong values from my old board i can measure direct from onboard connectiong pin of sensor to R4 and R58 4,7K Ohm my actual board give from pin to R4 2...

ok found it sorry
