alberto Posted August 1, 2003 Report Posted August 1, 2003 how connect the 3-axis stepper controller (cw technology) to pc? i don't understand theistructions.. please.....help me!!! :(Project link: http://www.electronics-lab.com/projects/pc/008/index.html Quote
Guest Alan9342 Posted August 4, 2003 Report Posted August 4, 2003 Hello all.I have completed the PCB for the 3-Axis stepper controller by CW Technologies and I am about ready to populate the board. However, I noticed on the PCB overlay there are six locations marked "JP1" thru "JP6". Are these jumpers? There is no documentation in the project file or the parts list for these call-outs. Also, I have tried unsuccessfuly to contact CW Technology about this question.Any help is greatly appreciated!Alan Quote
mixos Posted August 4, 2003 Report Posted August 4, 2003 The through is that the documentation is not clear. First you must not confused by the schematic. The schematic only saw the one of the three controllers that the pcb includes (UCN5804B).With the same way the other two are connected. So the x=6, y=7, z=8 means that for U1 that controls x motor you connect the pin14 to the 6 of the parallel port. For the U2 that controls y motor you connect the pin14 to the 7 of the parallel port e.t.c. The same you must do for the x=2, y=3, z=4. Did you get the logic of it?But if you build it with the pcb the things are easier. The only thing you have to do is to connect the numbers that you can see on the pcb overlay to the same numbers of the parallel port connector. Quote
mixos Posted August 4, 2003 Report Posted August 4, 2003 Yes these are jumpers. They are used to define the mode that each stepper motor works. The modes are: two-phase, one-phase, half-step, step-inhibit. You can see how to set by reading this table:L means LowH means HighIf you put the jumper then its Low (it short circuit the pin with ground) otherwise is High. So for each motor use the above table to set the modes.J1 changes the pin9 state and J2 the pin10 state of U1J4 changes the pin9 state and J3 the pin10 state of U2J6 changes the pin9 state and J5 the pin10 state of U3You can read the datasheet for more info on the UCN5804BAlso check the manufacture's site Quote
alberto Posted August 4, 2003 Author Report Posted August 4, 2003 mike thanks! but I still have some questions!-what is the tension to be applied on the Pin +- Pwr? -how connect Limit pin?-x-y-z home? seen that many people have found problems with the wiring of the circuit, drawing a detailed scheme and putting it at disposal of everybody on the site would be better.alberto Quote
Guest Alan9342 Posted August 6, 2003 Report Posted August 6, 2003 Has anyone out there built/used one of the CW Technology stepper controllers? Any input as to ease of setup/use? How about types of software. I have read in the circuit documentation that it was designed to use dancad. Has anyone attempted to use another program such as K-CAM? Quote
mixos Posted August 6, 2003 Report Posted August 6, 2003 The input voltage can be anything from 8V to 35V, but keep it at the voltage that the motor uses and not below 8V.As saws the schematic. You take a switch and connect the one pin of it to the ground. The other pin to the pin 10 of the parallel port and from that pin with a resistor to +5V that exist at the output pin3 of MC7805. By the way there is a place on the pcb for that switch.For home switches you follow the same practice. Also check this artwork to see how to connect it to pcb. Quote
alberto Posted August 6, 2003 Author Report Posted August 6, 2003 dear alan i think that you can find more cnc free software in:http://majosoft.tripod.com/hobbycnclinks/body_hobbycnclinks.htmlThe 3-axis stepper controller can read other cnc software than dancad.In the archive software i had found "jalaCNC" and i think is a very simple and intuitive software in windows but i aven't try it yet.

alberto Posted August 6, 2003 Author Report Posted August 6, 2003 Someone has never tried to build a digital Display to show the value of the Cordinate x-y-z, to be applied to panel on the case where to accomodate the 3-Axis Stepper Controller? ;D Quote
Guest Alan9342 Posted August 6, 2003 Report Posted August 6, 2003 Thanks for the reply Alberto.Ok, I have built the board (cw tech.) and have it connected to my pc. Before I attempt to power the thing up with steppers attached, are there supposed to be any "power resistors" in line with the motors? Since I cannot find any further information on this stepper controller board I am at a loss with regards to the output of the thing.I have the entire setup sitting on my lab bench and am using a HP triple output power supply for the testing. The stepper motors are NEMA 23's 6 wire 5.2v/phase and 1.4a/phase.Any concerns, comments, or warnings?!?!?Thanks,Alan Quote
alberto Posted August 9, 2003 Author Report Posted August 9, 2003 wich software to use with the 3-axis stepper controller?i'don't like dancad. Quote
Guest Alan9342 Posted August 10, 2003 Report Posted August 10, 2003 Alberto, I was going to use KCam, however, I have found what everyone was telling me about windows based software is true-it's "choppy". The program did run my stepper controller setup though.So I tried to use Turbocnc. Could not get it to talk to the controller board or move the motors at all.I then tried Dancad. The only thing I can get out of it is my parallel port 10 pin is in a high state and then the program locks up. I have searched for a method to put it in a low state (shorting to ground ect.) but nothing works. I really don't know where to go from here. Any suggestions? ??? Quote
alberto Posted August 24, 2003 Author Report Posted August 24, 2003 can i use the 3-axis stepper controller with the serial port of my computer if i use parallel to serial port converter? ;D Quote
EDY Posted September 13, 2003 Report Posted September 13, 2003 Hi. I have a EM-236 and EM-237 bipolar stepper motors that I would like to hook up with this project. However they need 36V power thus I can't use 5804 controler. What would be aduequate replacment? Oh and does anyone have datasheet for these two motors?Thanx Quote
EDY Posted September 28, 2003 Report Posted September 28, 2003 Nevermind my previous post. I figuerd that those motors only have 2 steps so they would be use less Quote
alheira Posted October 11, 2003 Report Posted October 11, 2003 How many people have a 3-Axis Stepper Controller project working?Each one who does please:How fine the project works?And what about the software?What kind of hobby work or aplication? Quote
cncmadman Posted October 14, 2003 Report Posted October 14, 2003 Worked for me. No problems whatsoeverWorks excellentTurboCNC (which reminds I need to send that guy 20 bucks)PCB milling and drilling, Wood carving, Aluminum RC car parts just whatever I feel up to Quote
jjwl89 Posted December 6, 2003 Report Posted December 6, 2003 can i only use 6 wire motors or are 4 wire motors compatible too? also digi-key has discontinued the 0.01uF 63v monolithic capacitor (P4914-ND) and the slide on sink for U2 (HS125-ND Quote
jjwl89 Posted December 6, 2003 Report Posted December 6, 2003 (continued from my last post) does anyone know where I can get these parts? Quote
cncmadman Posted December 8, 2003 Report Posted December 8, 2003 I am pretty sure only 5 or 6 wire steppers will workI purchased my parts from www.circuitspecialists.com Quote
alberto Posted December 10, 2003 Author Report Posted December 10, 2003 CNCMADMAN, G00 means quick point to point positioning and G96 means constant cut speed so your expression "G00 G96 X.0 Y.0 Z.02" does not have sense. ;) Quote
cncmadman Posted December 11, 2003 Report Posted December 11, 2003 You are wise to notice!!!!!!!!!!!Many great machining to you! Quote
MP Posted December 12, 2003 Report Posted December 12, 2003 Ahh! The last post reminded me. Here is some information regarding the CNC programming for those who want to write their own programs or for those who are just interested. Not sure where I got this file, but it has lots of information regarding the CNC commands.MPCNC_Programming.pdf Quote
