Thanks for clarifying everything Al. You just saved me a headache!!

Thanks for the reply. I am familiar with the backlash controls in Mach3 but what I want to figure out is if the Servo Encoder feedback compensates for this backlash within a closed loop system?
...

I plan to add either a set of the mini Pittman or Faulhaber servo gearhead motors with encoders to drive a small 3 axis closed loop CNC setup. So the servo drivers will be connected to the encoder. ...

O.K. that's a huge help! Thanks for putting this on paper and I will try to cut shortly.

Feasibly I could use a 3/8" bit which is the same size as the hole being slotted and just run it slow like 0.75" per minute. That would also work.

I cannot angle the piece because there will be a...

I have attached a PDF which gives more information. It would be cut on a CNC Router or Mill (3 axis). The depth of the slot would angle up like a swimming pool where its deep then gets shallower...

I need some help or guidance on how to program a slot which starts at -0.10" depth and over a 4" movement it ends at 0.00". So a gradual movement from -0.10 to 0.00" smoothly over 4".

Slot width...

Yes I am aware of Byers however they are priced well out my budget for what I want to do. I am hoping to find someone that has precision equipment to make these in their small shop versus going with...

Does anyone on CNC Zone happen to make precision Worm Gears in 4" and 6" sizes for standard off the shelf worms or can also make the matching worms. Materials of interest are bronze or aluminum with...

Yeah, exactly like a hollow mill or a plug cutter except for stainless steel. Anyway I'm guessing that I'm out luck and will just need to use my slide stage.

Probably the best way for me to set...

I have a Hardinge Lathe DV-59 and wanting to machine some screw ends where they are current 1/2" O.D. screws down to 1/4" O.D. for fitting into a bearing housing. I only need to finish about 0.40 to...

Does anyone know where I can find the a plastic solid rod with the following characteristics:

1. High tolerance for the rod outside diameter. I need rod sizes such as 1.00 inch and 1.25 inch...

Excellent. Thanks for the help!

Can someone point me in the right direction. I've found numerous vendors on places like ebay that carry affordable Nema 23 mounts but not having any luck for Nema 34. Anyone have any tips /...

Does anyone know where to buy a large OD / ID (Outside Diameter / Inside Diameter) tube made of steel or aluminum?

I am trying to locate a tube in two sections that measure around 14" to 18" OD. ...

I recently acquired a MaxNc 10 and need a little help from someone that knows this instrument and hopefully has the instruction manual.

1. What is the collet sizes used? This one only came with...

First I'm new to lasers but did some research. One thing I quickly discovered is photo engraving is not easy!!!

A lot of people are using Corel Draw or similar programs. But one product which...

I see a lot of talk about building a laser on CNCZONE but curious if anyone out there has actually done this?

I'm deciding to sell my laser kit that I assembled consisting of a 25 watt co2...

O.K. I'm getting somewhere... So if I went with the $25 kit for this motor then is it o.k. to get a 12 volt 12.5 amp power supply or a 12 volt 17 amp power supply even though this motor is rated at...

I looked at this kit.. My hope is to find this or something similar already assembled. And the other catch is the power supply... I need something near 8VDC at 12 or 15amps.

But I may be stuck?

I am trying to find a fairly inexpensive variable speed controller and power supply to run a small R/C type of engine. As an example here's a possible R/C 8.4VDC engine :: ...

I am trying to find a company that sells to the public Aluminum Profile to make Linear Actuators.

The only profile I can find is by Techno-Isel : ...

I looked up the RF25 and it looks just like my Harbor Freight. I see the RF31 and RF25 clones that appear the same depending on which company selling them...

Any chance you could send me some...

I've typically use small router end mills (1/8") and then cut out the holes or partially drilling them (i.e., dotting the hole about 0.05" deep). The problem I've encountered is I need to use a...

Thanks, that answers my question.. I was hoping to just use my CNC Router for metal drilling but looks like I need to get a benchtop CNC Mill for that part.

I've searched the forums and everything I found was related to the small / mini systems. Those seemed to be plagued by problems but I haven't found any posts regarding their larger machines?

The...

I have a Harbor Freight Rong Fu RF31 copy and would like to make it CNC. I see a couple companies on the web that offer CNC completed RF31 machines (they're fairly expensive) but curious if there's...

I do a mix of cutting and drilling in soft metals. What's really painful is there appears to be no good way to use a drill bit on a router like Porter Cable.. Oh course, a drill chuck would change...

This is a lame question but guessing someone out there has an extremely good answer.

I'm wanting to build a fairly large CNC table designed similar to an old graph plotter where the X and Y are...

I'm about to either buy a chinese laser engraver or convert my existing CNC router to a laser engraver.. Could you let me know what parts / kit / products / directions or whatever that you're using...
