Nothing was broken or missing. The next step in the construction was to install resistors R9-R12 and solder them in place. I just received the new Hobbycnc Pro Chopper driver kit. This is the third electronics kit made by them that I have assembled. Thanks for doing this!

3 axis HobbyCNC PRO Chopper Driver Board Kit
Can change this time delay. I have not used a BOB hlbbycnc my routers and I like that everything is on one pcb instead of a seperate pcb for each axis that are wired together. Everything was well packaged. When I plug it in with a motor attached the chips become burning hot. Big blobs are NOT what you want.
Building the HobbyCNC 4 Axis Stepper Driver
The only difference is that the components for the 4th axis are not included with the 3 axis kit. Hopefully someone is still around to see this post but I have a question about the board and driver chips. Jun 22, Kit contents Here are the basic components of the complete chppper axis Pro board kit.
HobbyCNC does not provide a schematic with the kit, but the silkscreen on the PCB and the step by step choppeg make it easy to put the board together. Jun 21, Bipolar stepper motors cannot be used. Each axis adjustable throughout this range. After each step in the build I checked the solder joints under a magnifying glass.
We will also prp everything neatly and safely into a custom case. Here are the basic components of the complete 4 axis Pro board kit.
hovbycnc It is easier to find a cold solder joint as you add parts to the board, rather than checking the entire board in one session. The circuit board for the prp axis kit and the 4 axis kits are the same. Now that the driver board is working we can wean ouselves from the benchtop power supply by building a dedicated power supply.

The PCB is double sided, solder masked and silk screened. Posting Quick Reply – Please Wait. Accepts 5, 6, or 8 wire stepper motors only.
These resistors have multiple legs and have to be positioned correctly. Once the resistors are identified, I placed them in the proper positions on the top side of the circuit board. If you plan to do many more electronics projects, a fixture to hold circuit boards might also be a good idea. I also bought the 4th axis components after the fact and soldered them in place for future use on an A axis.
I think It got hotter than F, it would burn on touch. Apr 07, Results 1 to 11 of The motors I have are 3amp per coil, the max of the board but I wouldn’t think that should be a problem.

I then flipped the board over and bent the leads to lock the resistors in place on the board. Nothing was broken or missing.
I purchased a package. The board also provides 5 inputs that can be used for limit switches.
