If you have an 8 wire motor (23-205-DS8) you are partially correct. The motor has 4 coils and you are connected to each end. Connect the yellow and blue together and also connect orange and brown...

RC Junkie, We have got away from you originally and I would like to know if you have it working? Let us know.
John

Thanks for the reply's. The thread started in 2008 so I am okay now for circuits.
John

You are correct but from the explanation I read is that he is only using 4 wires. He does not mention anything about the other 4. If they are not connected they are not going to work. The motor he is...

I am not sure what your board is like for operating but if it is only using 4 wires then what have you done with the other 4. The com wires yellow and blue should be connected together and so shoul...

I have not used my foamcutter for a couple of years but will dig up some of the info later. My cutter is also 3/8 x 16tpi and the steps for running foamworks from my pc is 3217 steps.
Hope this...

Along with the rest that is mentioned, have you actually taken an amp meter and measured the draw on the transformer. You are working at the maximum now and you should be using a larger transformer....

Dennis,
Not sure how large a balancer you need but I have been working on a home built one for my small turbine. I have the schematic and also the other instructions that I downloaded a while...

I have the same board and using it on my foamcutter. I also have a NS board that I stripped the components off and checking the traces I have a question. What voltage are you getting on U5 (LM317)?...

My motor has the 110/220 on the plate but what stopped me from going to the lower voltage was the amp requirement printed on it. The 220 side is 16 amps and the 110 side is 20 amps. Was not going to...

I have the 1977 and run it on 220. I don't think it can be changed over. I installed a plug by my panel and ran an extension cord to it. The cord is 12 guage about 15 ft. long and runs fine. If you...

I don't have a schematic of the board but if somebody has one it would be appreciatted. Another question is if anybody has a board could they check to see if there is continuity between pins 27 and...

I am trying to learn a bit on how to program a chip. I bought this board to do some testing and will get something better later. After spending quite a while trying to get something to run (leds...

Phil is right about checking the caps as I now remember splitting the case on (C14) and changed C12 and C13 just in case they where weak from the extra voltage. If you don't know how to check them...

I would change U5 and also U7 and if your fan is not working change U6. I had the same problem last fall and I would not be suprised if some of your drivers are also shot. My problem was unhooking...

I have mounted steppers on my mill/drill table and am going to operate them with the pro board. I have a 4 axis Hobbycnc pro board operating my foamcutter and want to use the same power supply. They...

The cost of the chips and having to purchase 25 of them makes any of the other boards very reasonable. This is why I went with the Hobbycnc board. Those prices are just gouging for a do it yourself...

Phil,
Thanks for the info and will see if I can build something to go with the circuit. I don't have any boards but will build 2 controllers for manual operation. I don't want to hook something...

I have searched for a diy method of how to manually control a 6volt 2 amp stepper motor. I have a medical problem with my right sholder and want to be able to move the table on my mill/drill using...

The diffuser looks quite different from the norm. I have also seen the tubes done on another site a couple of years ago as an experiment. They where squeezing with a pair of side cutters at opposite...

Go to Digikey's web site. You will find what you need on a search in the online catalouge. If you need to mount a large resistor I prefer the alum. housed ones as they have the heatsink. You should...

Tried the site in Saskatoon and have a question. There flyer does not open and has not been updated for quite a while. Does not help when you are in another province.
The way it is going you can...

I use Foamworks also. One was to much money for what I wanted to do and the other one I never did get working right but it is still loaded. Maybe play with it after to find the problem.
...

Check out Hobbycnc or some of the others for do it yourself on the electronics.
John

I think it would work also as I am in the process of converting my mill/drill using the Hobbycnc pro board with 300 oz. steppers. I am going to buy a separate board for it as the one I am using...

I use a bow for my wire as I did not like the idea of putting tension on the towers. The bow is on insulated pegs trapped between a couple of fibre washers and the weight of it keeps it there. My bow...

Mark,
I agree with you on the turbine disc as being cast except that you can make one for the Kamp's book turbine by turning a disc then cutting the profile of the blades and twisting them by...

I have the Hobbycnc pro board and use the 80oz. motors on my foam cutter. I am using a 15 amp supply at 24 volts with no problems. It is overkill with the amps but I believe they reccommend 10 amp....

I don't have your setup but maybe you could find the rating and replace. Is there any numbers on it for a start. IE how many microfarads, voltage and what size is the burnt one. From there it should...

Larry,
I agree with you but also noticed you never gave any info either.
I am from a small town and I have been an RC modeller since 68 and I have several hobbies which all come together...
