Hi all,
Enabled max-nc 10 wave drive.
I have x control and z control but no y control? What am I overlooking?
-Stepper speed set to match x/z axis
- I noticed that pins/pots - motors have no effect, other then enable disable. Alll 3 axis are enabled. I assume this is normal from other threads
- I also switched back to Maxnc control program on my old pentium and y-axis worked fine. I also swapped wiring to check the stepper and it worked fine. So its not the motor.
Any help would be great.

David,
Since the x & z work, and you have swapped the one of those for a check of the non working y axis,
suggests to me that you don't have the pins defined properely for the y axis. When in MACH go to:
- CONFIG>PORTS & PINS >MOTOR OUPUTS> enable y and check pins / active settings are correct
- CONFIG>MOTOR TUNING> check that you have done y tuning
If the step and direction signal is generated anad confirmed out of the PP then next step may be wiring.
Repost if that dosn't fix it.

DAVID,
Did you get a manual for the MAX CN. The comments made in my other posting pertain to using MACH 3.
I don't know anything about the Max CN software, and after a quick site check, they only mentioned MACH2.
Since they have custom screens i was just wondering if you are are using the lathe screen for the mill.

Hi, David, Rich
I'm Thinking:
Max NC uses ether Quadrature or Rollover (Wave) on Most of there Drives, If Stepper, Max NC 10 "Checked" on Config, Ports & Pins Page.
Then It's as follows, Port's and Pin's settings have No Affect on the settings Just Motor Tuning Settings for the most part.
You may need to Re-Wire some Pin's to check it out/get it Working.
"Z" axis pin's 2,3,4,5,
"X" axis pin's 6,7,8,9,
"Y" axis pin's 1,14,16,17,
It uses all the output pin's so I don't think it has an Enable pin from Mach3.
In Config, Ports & Pins, Output's Page, No pin's selected.
In Config, Motor Tuning, Set Step & Dir. Pulse's to 5
Then Continue with Motor Tuning and Such.....
SEQUENCE For Z Pin's
Z | 2 | 3 | 4 | 5 | Pin's
A | 1 | 0 | 0 | 0
B | 0 | 1 | 0 | 0
C | 0 | 0 | 1 | 0
D | 0 | 0 | 0 | 1
SEQUENCE One Dir. A,B,C,D,A,B,C..... or Other Dir. D,C,B,A,D,C,B......
Let us Know, Hope this Helps get you Going.

Chip,
Just to clarify, there are 8 steps per sequence. This is a half step pattern.
SEQUENCE For Z Pin's
Z | 2 | 3 | 4 | 5 | Pin's
A | 1 | 0 | 0 | 0
B | 1 | 1 | 0 | 0
C | 0 | 1 | 0 | 0
D | 0 | 1 | 1 | 0
E | 0 | 0 | 1 | 0
F | 0 | 0 | 1 | 1
G | 0 | 0 | 0 | 1
H | 1 | 0 | 0 | 1

Hi, Darek
That may be true, Didn't remember all the "fine print" for full and half step modes or which one Max NC used.
Thanks, Chip
-
Thanks for tips everyone.
I'm still working on the issue. I'll test the pin outputs tomorrow.
I still have no idea why it works on the original maxnc software and not this.

David,
If you are using the same PC and connecting cable it looks like Mach is not outputting the Y axis. I was configuring a MaxNC CL profile before and lost the quadrature output. I started a new profile and the output was restored. You may try reloading Mach also if the previous suggestion does not help.

I've tried the machine with a second PC to eliminate the problem. Both have no y control.
-
What version of Mach3 are you using? I will load it up and see if I have the same results.
Darek

Hi All,
Just tested the pins - and it follows Chips layout - axis pin's 2,3,4,5, axis pin's 6,7,8,9, axis pin's 1,14,16,17
This confirms my theory that its a software related problem, since the machine works in maxnc perfectly, I have x,z control in Mach. I've swapped motors on Y with a known good one and it still doesn't work. And finally the pins match what Chip was saying was the correct layout.
I've also tried a second PC running the same version of software.
Running the latest demo version.
This is interesting.

Hi, David
I've checked 2 versions of Mach3 hear for outputs both seem to have outputs ver 3.042 being one of them.
A friend has one of these mills, I'll see about checking this out.
Chip

I also tried an older version mach 3 something like version 1.83
-
Still looking for the Y-axis. Any new suggestions?
Thanks.

Dave,
Try this xml for your mill and see if it works. I had my maxnc running with this configuration. You may have to make a few adjustments in the motor tuning, etc. to suit your mill.
Jeff

Progress.
Jeff, that got all three steppers buzzing! Now I just need movement. Any suggestions? Prio I could never get the y-axis to buzz, but the other two moved.
-
Ah you have CL mode selected vs. wave drive.
-
Hi Dave,
Was just wondering if you've had any luck with getting your axis's to jog. There are lots of documention on the MaxNC 10 here in the forum, just do a search for it.
Jeff
-
Not yet. I've been able to get them to buzz (spin) in all directions under CL mode. Changing motor settings, I can adjust the frequency of the buzz..
And again under waveform mode I have two directions, but no third.

Hi Dave,
Check out this posting in the forum and see if it helps you any.
http://www.machsupport.com/forum/index.php/topic,1319.0.html
I'll keep searching and see what I can come up with to help.

Hi, David
I took Another Look at this, Set Mach to Max NC-10 Mode, Pic 1.
Then set "Motor Outputs" to Pic 2 or 3, Exactly as shown in Pic's.
Pic 2, Max NC-10 Half Step Mode, ( It keep's 2 coil's active with each step).
Pic 3, Max NC-10 Full Step Mode, ( It keep's 1 coil active with each step).
If an axises Run Backwards, Will deal with that in a bit, Let's just get All of them Running First.
Sent you a PM message, Click on your messages top of this Screen.

No improvement with "y" control with the above settings.
Half Step mode changes direction of x and z axis otherwise no change.

Hello David,
Here is another xml file for you to try. I have one more buried in my achives somewhere that I'll have to dig up. Don't get frustrated because I think I had this problem at one time.

Hi, David
I finally got the MAXNC 15 to test with, It work's just fine Hear.
Hears the XML file I used, Give it a try, It's setup in INCH Mode.
I didn't spend allot of time verifying that the steps per values or velocity/acceleration are set/optimized eather.
If this doesn't work on the same computer as max-nc software works on then It's got to be a Window's / Printer Port Issue.
Using ver.027, Lic or Un-Lic ver of Mach work hear.

Hi David,
As Chip said, it may be a printer port issue. Try setting your printer port to EPP in bios and see if that corrects the problem.
Jeff

Hi, David
Did you get it working.
Chip

Hi Chip..
Thanks for your help!
Your little printer port tester program is really helping. This is what i found out. 4 pins per axis. Those 8 pins for x,z axis are each reading 3.5v(or very close to that) when turned on at the board input. Axis y pins are only reading 1.7v when on at the board input. Connecting pins 18-25 together. (didn't help).
I've already re-soldered the x-axis printer cable to the y-axis input on the board and it worked correctly., thus eliminating the board as a problem.
Next step is to read the voltage directly from the computer port. If they are good at the port, the cable could be shorting or bad.
What do you think?
