Can anyone help ? I have X-carve , j-tech 3.8w laser & lightburn installed , 1.1g grbl & I can not get the laser
working for love nor money ! all settings changed in lightburn as per instructions . Problem is I am only showing 2.15v at the back of X-controller when testing spindle PWM & Gnd with the multimeter J Tech say I need 5v for it to work ! image|400x300
I am at a loss as to why ? They were bought new from Robbosavy Sept 2017 & for reasons I won’t go into I have only just been able to set up the laser … still in the packaging & still brand new , first off nothing would work , after a day or so thinking I had set Lightburn up wrong , I got in touch with Jay from J-Tech & got to say he has been very good at replying etc ! After trying the tests I eventually found out that the new plug was not working So Jay kindly sent another out ,which off the bat worked the lights & fans on the laser , but now it still wont fire & after Jay talked me through the tests We have now got a lack of power at the said back connectors ,Any one got any ideas ?
