JADAZI GRBL CNC Control Board for 3 Axis Stepper Motor Controller

Works perfectly, a very good buy for lightburn software.One thing that had me perplexed for a while - my laser didn’t fire but then I realised that the jumper that Ive highlighted ships in the spindle (SPN) position, if you are using a laser swap it as shown (LSR). Also make sure your laser is connected properly to POW, GND and PWM

A nice board with plenty of function, works well with air assist pin with relay, the stop pause resume pins, are very useful, the board in some sites say it is 32 bit, but unable to confirm, Feungsake sell the same board as claimed 32bit so maybe it is although not stated by Jadazi, I found that Using a Solid state relay was a better option than Mechanical ones unless using a 1n4007 Diode to supress the spikes from the relay, that pauses the board, this board is sensetive to power spikes even with a small compresor on the same ring main can cause a stall brown out, Generally I was very pleased with the board, but after my 2nd one died that had the kaser spindle jumper replaced with a switch ( nice touch) from the same reason as the first that lasted way longer then a month this one did, as the PWM & TTl died to fire the laser "Again" even with a using a seperate power supply board for the laser, I will be looking for an alternative GrbRBL board replacement, as this one is not cheap compard to others! just shy of £60 on two boards now I will not be making it £90 up the swanny!

First things if you are the kind of person who needs a manual and hand holding then dont buy this you dont need a lot of technical knowledge but there are too many reviews on here sating the seller wont help them.Know what your buying! its a controller only how you set it up and use it depends on your application you cant expect the seller to help you with this!I replaced a CNC controller with this easily and swapped out a K40 laser controller (that was a little more effort) but both worked perfectly once set up.

Was working fine when tested it but then one laser died and I had to use the spare. Then the spare started to go funny and I found that the pwm/ttl went from 5v to 7.5v. This has broken my laser and 3 stepper motor drivers!Not happy at all.

arrived with broken C17J voltage regulator, had to resolder a new one, seems to work fine now.

The media could not be loaded. This is a great little board I have had 6 of them 1 did fail after about a year but the rest are all working perfect.

Couldn't recommend this produce enough. Wiring diagram is very good. It's flashed with GRBL 1.1. once connected I then used UGS to change the step size by changing $ settings. Was my first experience of setting up control card, but only took 30 mins to cut old connection blocks and replace.

The card works in some way on grble cnc but does not feed back to the software. There is no manual or manufacturer support on this basis I'm reluctantly returning the board. It is important sellers provide support for items they sell. It maybe a simple code fix but without any information Im stuck no jumper info settings etc. Like I said the board drives nema fine, the relay works but there is no feedback to the computer meaning when the stepper moves its no shown graphically on the software unlike every other board I've tried.
