Thanks!

OK, thanks!

I took one of the capacitors by a motor repair shop because my meter wouldn't read high enough for 4700uf. They said it was bad. So I ordered another capacitor but in the meantime ordered another DC...

Mine has a cut capacity of 49.25"x82.5"x120.5" and can cut 2 48x36x120 blocks at one time, has 2 axis mode, 4 axis mode and 5th axis turntable. I machined the 10'+ x axis guides from 1.5" cold-rolled...

So that's good? I wonder why the power supply died?

The PS has 2- 30Vchannels and I was running them both in series at about 26V each, so I suppose it was 52V. The current was set on max (5A) but the meters were reading 4.6A

Thanks, that is basically what I had before it died. :( Dr Meter HY3005F 3 Variable Triple Output Linear DC Regulated Power Supply 30V5A | eBay
except mine was an "Arksen" probably made at the same...

This is the cutter I built. It can handle two 3x4x10 blocks at once, has 4 axis capability and a 5th axis turntable. But I was using a DC power supply to heat the 84" Nichrome wire and for some...

This is the wire which is between the controller and the motor. Coboc Model SPW-CL2-4C16-100-WH 100ft 16AWG CL2 Rated 4-Conductor Enhanced Loud

I used short pieces of another type wire between...

It's not Cat 5 or any kind of ethernet, It's multistrand 18 gauge, I think. I will check it in the morning.

Yes, it's 8 wires and connected parallel.

Jeff, I tried both settings and it still vibrates/rattles.

Thanks. I can sleep better knowing about that one now. ;)
Can't wait to get to the shop to try the settings you showed me.

One thing I'm wondering:
The #4 switch on my drivers is set to "0" (down position), which I read on the Automation Tech. site is "half current". What does that do/cause? Also, the #8 switch is set...

Thanks Jeff, Yes, it's set for inches. I will try that tomorrow. Sounds good! :)

Yes, parallel port with "C10" breakout board.

About 3.1416"

It only has the 425 oz in stepper with timing pulley on one end, the same size idler pulley at the other end and a spring-loaded "omega drive" between on the Y axis(keeps the belt tight and helps...

Thanks, this is close to the speed the foamcutter will normally run, except for rapids.

Since this will be a slow moving machine, would setting the microstepping to like 1/32 or 1/64 solve this?

It does the same at 150 ipm....not too bad at 300ipm

It's set on 35ipm right now. I will go and check.

Thanks, here's a clip....

The machine is a fairly large 9x11x4 hotwire foam cutter driven by timing belts. I'm using 185 oz in motors on the Y axis and 425 oz in motors on the X all with KL4030 drivers,. I have my DIP...

My cutter's Nichrome wire is 83" long and 24 gauge. I'm figuring it needs 37V and 3.15A to reach 700º and I'm thinking it won't even need to be that hot. With a 22 gauge wire it only needs just a...

That's what I set the drivers to, when I installed the 185's on the Y axis. I will check the drivers tomorrow.
Thanks

I don't think I did. But I can double check tomorrow. I did reset two of the drivers because I removed two 425 in oz motors and replaced them with 185's to reduce weight on the Y axis. I reset the...

Thanks
I'm using the KL4030's from Automation Technologies, and the 425 in oz steppers from the same. I had these running smoothly, once before, but the computer I was running Mach3 on died and I...

My hotwire foam cutter is close to being operational. But the motors on the x axis are vibrating/rattling. I found something once which explained "resonance" but I don't see anything in the motor...

Thanks!
