Using dull cutters or tools that are not on center will cause overheating the material and work hardening.Although,yes,you do want to take a decent depth of cut while roughing. I cut a lot of...

I have a Boss 5 that I retrofitted with Keling KL-11080 stepper drives, using the original steppers, and Msch3 control with a Smooth Stepper motion control board, also using a 5axis CNC breakout...

If the part is flat and not distorted before sanding it, then you are creating too much heat with the sander. Maybe just use scotchbright by hand.
if it actually distorts during machining, then you...

There really isn’t enough information to make an informed recommendation here. As mentioned above, what diameter cutter? And are you using coolant? What depth of cut? How far is your tool sticking...

I can't get Bobcam to post out arcs/circles. I get only point to point. It's too much code for my Mach3 control. AM I missing a setting in Bobcam? I'm sure it has to be an option.

Plunging stainless like that is hard on an endmill. I would probably use a carbide drill and around a .234 drill and then mill using a 3/16 or 7/32 carbide EM. No center drill since you are milling...

I machine quite a bit of stainless. If you are running 700 SFM you will be burning up inserts. I run about 325 SFM with 304 and a feed of .01 to .012 IPR. You need a slower speed and a harder feed....

The feed rate is determined by
(rpm X chipload( I.e.- load per tooth) X number of teeth)
recommended chipload per tooth should be available from the EM manufacturer, or you can just look it up in...

Hey Steve,

My goal right now is to get the thing running as inexspenively as possible. It will be a couple months before I can afford to buy the VFD and an ESS. So I was just hoping to get it...

I will check the line voltage to make sure when I get that far.

i spent a couple evenings after work removing a few things. I have removed th 3 reactors for the axis drivers. Removed all the...

.It appears that your machine was purchased with a very basic IPS syetem. the one in the manual is an option for conversational programming. If you want the extra functionality you can purchase any...

Ok, so it sounds like you both highly recomend a VFD. So will it produce the same amount of power either way? I will look at VFD's now.
So with a VFD I can just run 220 to it and skip the RPC and...

It would be nice to have Servos on my mill instead of steppers. A tool changer and enclosure too, I'm jealous. My next one will be a VMC I think.
I sure would like to see your setup. Do you think...

I do have the schematics. I don't completely understand the schematics they give. I mean, some components are labeled so I get that stuff. But some of it seems vague to me. I will take another look...

Oops

Unfortunately not really. I did figure out how to get the motor to move both ways. So I now know how to wire up the controller to the motors.
I just don't know what to do about the power supply to...

You can make that with a groove tool that is as wide or wider than the lead of the thread(I.e.- 12 TPI = .0833333 for example.
So copy your thread cycle, then past it into the new tool. Change the...

Try that. You shouldn't need both lines. I don't see anything obvious in your code that would make it go past X0.
I ran a TL 1 for about five years. Pretty good little machine really. And easy to...

Thank you for the input.
I will get to making a plan and sketch it down.
I will come back and record it here when I g t that done.
I figure I will document everything here so it's easy to...

Hi everyone. My name is Rick. I picked up 2 Bridgeport's last year. One is a Boss 5 mill and the other is an EZpath Lathe.
Anyway, when I bought the mill, I had to remove most of the head to get it...
