So what you are saying is that the pc is locked?
All else seems ok from what I can tell.
I am not even going to try messing with the pc.

I did switch the lead and used the autorange and also selected manual range and 10amps
Still no readings when jogging or stepping.

Darek,
What positions should the switches above the tape be in?
THANKS

I have 0 volts when enabled and 24 when e-stopped

Here is what I did today to check the axis current:
With the power off removed FU13
Power on overtravel light on
37.8-vdc not steady but slightly decreasing
press overtravel
80.4vdc steady

I did as Derek said and do get movement on the steppers.
Once I get this thing running I am going to post a lenghty thread on what guys talked me through so it may help someone else.
Seems alot of...

Thanks Darek,I will try this but want to make sure I do it correct before I do it.
Do I want to jump #1 to #2 for x-#3 to #4 for y or #5 to #6 or do I want to jump to ground?
I am no electrician so...

Sorry Darek I see what you are asking know.

If you remember I posted...

Can these be checked in the circuit?

THANKS

I am checking the ones behind the smd boards.
THANKS fro the replys!

I found a little info today on checking the diodes for each axis on the panel behind the SMD boards on the heatsink.
I checked all of mine by going from the screw to each side of the diode and have...

When i got the machine the spindle would run as long as the power was on no matter...

Someone has this wiring really messed up and the manual is real hard to understand for...

Thanks for all the input.
When I was converting my Smithy 3 in 1 over to cnc I was using EMC.
My hope was too come up with a true cloosed loop system.
My machine already had readouts on it with...

Thanks for the responses.
I checked, the jumpers are set for 220v h1 and h3 jumped and h2 and h4 jumped on T1.
T2 is jumped z1-z3,z2-z4,y1-y3,y2-y4,x1-x3,x2-x4,z3-y4,z4-x3,y3-x4,print shows this...

Can anyone talk me through adjustment of the regulated powersupply?
I checked output on it again and still find 1 wrong voltage.
The manual refers you from 1 section of the manual to another that...

After much time spent on this Series II Boss 6 and getting nowhere
I have decided to do a retrofit.
I would like opinions from you guys that have done this on whether you are happy with conversions...

Another thing I found was a voltage test on FU12,FU13,FU14.
The manual checks voltage on these fuses for the axis with power on but the limit reset not yet pushed.
The voltage should be 38-42 and...

Thanks again George.
I have looked at this thing all day today(Cold outside anyway)
I pulled the X axis limit switch covers off today and find they are wired normally open and close when tripped....

Thanks for the reply George I do appreciate your help.
I have been studying the drawings and as of yet I don,t understand how the limit switch circuit works.
The drawing shows the limits normaly...

I also have all the prints and it would be impossible to get things going without them.
I did find someone had jumped out the spindle start switch and thats why it would come on as soon as power was...

Thanks for the help George,I did try pressing the button even though it is not iluminated.
I see by reading the manual it is in a limits condition and that these lights will be lit.
I will keep...
