SmoothStepper USB / Re: Can't get spindle to turn on
« on: November 08, 2015, 11:51:43 AM »
I can, but it may be a week or two. I have my rpm match pretty well from 1200-3000rpm, but under that is way off. I have lost motivation on this project, been thinking of selling so progress is VERY slow. I will post back when I get the info

Now I got the pulse width down to 28.8 as that is the lowest number that puts out 10vdc at 4000rpm command. Problem now is, when I put in the s2000 command it drops to 3.8vdc..... thought it would be proportional...... How to fix this?

more progress. Just messing around, I had set my spindle to 32khz in the ess config, then the pulse width to 40, and what do you know, I got voltage! I turned it up to 80 for the pulse width and I got my full 10vdc! Now time to hook it up to the Hitachi VFD and fight those issues.....

Okay, progress. I now can get the relays on the c32 bob when I issue a m3/m4 command now that I know you had to go into the ESS config and turn on the dir/step there. Still can not get any volts(other than the constant .4vdc) out of the analog signal unless I set the step active low.

I can not get a 10vdc signal on my analog output from my c32/ESS setup. I measure .4vdc constantly, but can not get anything else. I have tried to follow the manual, and no luck. I can get 10vdc to the analog, but only if I use step low active, but can not shut if off then unless I uncheck low active. When I do get that, it shows relay #1 active, if I check direction low active, relay #2 and axis 6 (rj45 port) show 1-14 and 1-16 are getting a signal. So it is obvious that I must have my pin setup wrong somehow.

I use mdi and type in s4000 m3 (top rpm) and it shows it should be running, but get nothing my my constant .4 volts.

I have tried several different setups, but this is what the manual says.
Motor outputs tab:
spindle enabled, step pin# 14, direction pin# 16, port 1 for both

It says nothing about outputs, so no change there

Spindle setup tab:
uncheck disable spindle relays
Clockwise (m3) output# 2
CCW (m4) output #1
not sure how these work and why the it states "outputs signals 1-6" when those are not valid outputs for port 1??? I thought they were only 2-9 on port 1 and 1,14,16 and 17 on port 2???
Motor control box:
check on Use spindle motor output
check on Step/dir motor

then I went to motor tuning
chose the spindle tab, turned up the velocity, moved accel to about 1/4, steps to 1000, step pulse 5, dir pulse 1.

Once I have this working correctly I can hook it up to my vfd (hitachi wj200) and deal with the "issues there", then I can actually start to cut some chips after having this mill for three years!

Please help, I am lost!

Nevermind, thought I had to reaarange the pinout according to the c32 to dg4s pinout, did not know to use a straight through cable, the c34dg rearranged the pins....

Okay, looks like I am finding the problem, just not sure why it is happening. I checked for voltage at the c32 BOB when the step and direction led's light up at the end of the eithernet cable that plugs into the c34. I have 5vdc for the direction, and 2.5vdc for step. Now the end of the ethernet cable that plugs into the driver is not showing ANY voltage for step/direction, but is showing voltage for the 12vdc that comes from the c34 to power the logic circuit in the driver. So, it seems the problem is either in the wiring to/from the c34, or the c34 is bad? The manual for the c34 says nothing about pin in or pin out, so I assumed it was straight through? I wired it so the pin out of the c32 matches up with the pin in of the driver. I wish the manuals for these were better so noobs like me don't keep banging out heads against the wall like this.....

when I try to get my SEM servos to move using Mach3, nothing happens. I get the led's on my c32 to light up for step and direction, I checked with my ohm meter about checking the pins vs pinout, everything looks like it should, but no movement. It holds it's position, but no movement..... Green led flashing on the drive (DG4S)......I assume straight through pinout for the c34 board since it does not have one in the manual. I am relying on the 12vdc from the c34 to power the drivers logic circuit and did not hook up the 5vdc from the c32.

 I tried using one of the other servos, and still no luck. Holding power, but no movement with axis jogging. Might try hooking it up to another driver, but other than that, I have no idea...... I have a bad feeling it is a setting I am forgeting in mach3. How can I test if the driver itself is getting the step signals, no way to get a tester on it with the rj45's plugged in.

I might have damaged one of my SEM servos while tuning it, it started smoking and now has the burnt smell, and when I turn it by hand it has a spot that is pretty hard to turn, anyone have a spare or know of a good place to repair? I have a bad feeling about the cost to repair.......

thanks to anyone who can help, I am dead in the water until I can get this figured out.

General Mach Discussion / Re: Limit and home switches possible?

I don't know how to edit the post, so I will update. I only wired my z limit switches, which there are two, one for -, and one for +, but just started on the y and looked closer at the x axis and they only have one. So I guess I can wire all my limits in series and hopefully the homes in series?

General Mach Discussion / Limit and home switches possible?
« on: November 23, 2014, 09:43:31 PM »
My bridgeport came with axis+, axis -, and axis home switches and would like to use them all. I am planning on using shielded alarm cable and running it on 24vdc. I am using a ESS and c32 BOB and think I am going to use a c27 to use for my limit switches. This will allow me to use port 1 pin 11, 12, 13 and port 2 pin 16. So, if I run all my - limits in series, all my + limits in series, and home switches in series I think this will work? How does mach3 do homing, does it move one axis until it finds home, them moves the other until it finds home, and then the last axis until it finds home? If so, it should work, right? I don't have a ton of inputs available, but can have more if I also buy a c10 bob (might do it anyways to open up port 3 for more inputs). I really want to do this right the first time.

thanks in advance for any helpful input :)
