I'm sorry, you are correct. I do have it setup for -.01". The numbers are starting to blur together today :)

So how do I set the soft limits in EMC2? I have the limits set for my table in the configuration. I've had no problems milling down to 0 before. Only when drilling holes. For a quick fix I set my...

Thanks for the reply! I actually just found out what happened. At least the part about hitting the screw. Turns out somehow the clearance plane got changed in that pocket to .5"! So I fixed that...

So I'm new to cnc and I finally have my machine up and running after calibrating it.

So here is what happened. I made a jig that I could place a 3.5"x3.5"x12" block of wood in. I cut this jig with...

Final results are in! First I would like to thank you all for your help. It put me in the right direction to figuring out what needed to be done. I ended up tearing apart all axis's and doing...

So finally some success. I am now cutting to within .015 which is not the greatest, but far better than what it was. I'll try and make a few more adjustments to see what I can get. If that's the best...

Thanks for the calculations. I don't know where I went wrong on that. I'm going to try those settings to see if it makes a difference.

Yes, I have learned a lot with this machine. Now I'm racking...

So what settings did you come up with to get those steps?

I will try that as soon as I figure out how I'm going to fix the issues with the gantry. The tool was accounted for when the cut was made. That is what I originally thought was the problem was at...

Well after moving the X and Y axis around the table checking for backlash and how much I could move the gantry and Z axis by hand while locked into place I did find some troubling issues/weak spots....

Ok, I'll start off with a little info for you guys to think over while I run some test.

Settings in EMC2 are as follows

X Axis:
Steps per revolution: 200
Driver Microstepping: 10...

I will try those steps as well. When I was originally trying to calibrate it I was using the ruler that came with my caliper. I would assume that it is accurate. During test it would always go the...

The testing I have done has been both cutting and with an 1/8 sraight non-cutting bit that came with my collet that I can chuck in for measuring. I have tried calibrating using several methods you...

You are correct that there is no adjustment. The gears are meshed tight and the rack is perfectly straight. I have ran it at the slowest speed possible knowing that it has not skipped any teeth with...

Here are a few pics. Hope this helps. I can upload more specific if you request.

I will post some pics when I get off work tonight. I work 12hr. days on the weekends so it will be around 8pm. Sorry for the misunderstanding on the tension. I'm an electronics tech not a machinist....

I'm so new I don't even know what a dial indicator is lol. So I probably don't have one? The belt tension is very tight with no slack. How do I calibrate the steps? If it were losing steps then...

First off, Hi! I'm new to this forum and new to CNC. I'm not even sure I'm posting in the right section. I'll get right down to it. I bought a home built CNC with a cutting area of 2' x 4'. I wish...
