Keating Cross Road on the left side heading west just before you get to Co-Op. Couple of big dumpster with a sign scrap metal. Pretty sure you can dump in there. Not sure if you can take out. Never thought to ask. Of course just down the road is Metal Supermarket.

@DavidR8 Special directions for you. Go west on Quadra. Then left and left again past KMS tools. Then take Mackenzie and take the turnoff towards Costco. Go past Costco turnoff and a bit further. Turn left at the lights down to Sooke Road. Continue west. Then eventually north past Sooke. Then up to Port Renfrew and through to Lake Cowichan. After that across to Duncan.
Down until you get to Highway 17. North until the Keating Cross Road turn off. Don't take that. Lots of construction. Keep going to Mount Newton Cross Road. Hang a left and then left on Central Saanich Road. Follow that and head up past Keating Elementary School Hang a right and Metal Super Market is just on your left by Co-op.

Won't take you long and better than epoxy.

I love it!
 
Took some time this afternoon to bench test all the drives and servos.
Alas I think I have a bad drive as one will not allow me to test the servo without throwing a "lost phase" fault.

I can only think that either @YotaBota, @PaulL or @jcdammeyer (or all three!) have conspired to slow me down! :)

On the plus side, the new motor pulley showed up today and fit the motor shaft perfectly.

Brutal!

You missed a critical part, John. David should absolutely comparison shop against Hardcore Metals. The most direct route from MSM almost certainly goes over the Malahat.

Could you test the servo in another position? Just to weed out any other issues.

When I built mine, I had a X axis issue. Mach 3 could see the command being sent. The LED on the break out board was lighting up. So I thought it was the stepper for sure.

It ended up being one trace on the break out board. The same signal lights the LED but the trace was missing to the final output.

Yup, that’s what I did. I used one servo that I know is good and tried the three drives in succession. Two drives worked fine, but the third errors out.
 
If my communication with DMM doesn't go well I may end up switching from servos to steppers.
I hope not to but I'm having lots of trouble getting these to work.

I'm using stepperOnline ac Servos, I'm pretty sure they are actually made by DMM. When setup properly they work really really well, they do have several advantages over steppers so FWIW might be worth the effort:
+ Near silent
+ Way more useable power (flat torque curve), so you can move at crazy fast speeds
+ Closed loop.

Technical support that's an entirely different discussion. A bit like asking the kid at the C.T. parts counter for a brake light for a Mazda 323 and they need to know; color of the car? what engine? does it have A/C?

The manual actually has a fair bit of information.

One thing to look out for is that some of these drivers have a specified input voltage of 220V so don't assume 220V is close enough to 240 to not worry. When you look at the actual Vin max it's too low to be safe with 240V. Fortunately you can use a cheap 24V transformer in buck mode to make a suitable 220V supply, that's what I did.
