I'd like to suggest that you quit looking at exact stop mode and CV settings as the source of your accuracy issues. I say that because I went down that rabbit hole last week. You read about all my...

When I built mine I tried to make it so the resistance as you move the gantry across was fairly consistent. It's probably ok to have it feeling a little tight. Those Nema 34 motors are quite...

Just finished assembling my kit a few weeks ago. I didn't know about this website when I built my machine. Nothing really special to the design since I ordered pre-built electronics and a ready...

I ran into this also. I've been tearing my hair out for days trying to figure out what was going wrong on my Z axis and was emailing Ahren 2 to 3 times a day. I had great repeatability in the Z...

Ok I'm a happy camper now. Once I identified I was loosing 20+ mil when moving against gravity the manufacturer helped me fix the problem. The fix was fairly simple. The z axis ballscrew assembly...

I think I've possibly found the source of the problem. Since most of those details involved a lot of short moves in the 10 to 30 mil range I hooked up a dial indicator again. I had the bit in the...

I don't output both toolpaths to the same file. I create seperate files. Then between files I manually swap the bits out. Then I place the auto Z unit on top of the workpiece and clip the lead on...

Looking at the two pieces closer I'm convinced this isn't a constant velocity issue. Even when I ran in Exact Stop mode and running really slow like 25 IPM I'm having Z height issues. The curly...

Yeah I've double-checked it twice. The preview was with the same size tools. The roughing was a 1/4" end mill bit and the finishing pass was an 1/8" round nose bit. And I agree it doesn't appear...

No I hadn't tried that yet. I guess being a newbie I thought the settings from the manufacturer of the table were the max values I should use.

Here's a photo showing the two different attempts...

I've got a Pro CNC router from cncrouterparts. The motor for the Z axis is exactly the same as X and Y. They are all 960 oz-in Nema 34 motors. So I assume the speed difference is because of a turn...

Thanks Gerry. My machine can run quite fast but my Z axis is much slower than my X and Y. Do I need to lower the settings for X and Y so that Z can keep up? Cause it seems like if I run the tool...

Hi all,

I'm just getting started learning Aspire and I was attempting to do the Gingerbread house free project. I was unhappy with the results of the first piece. I did a roughing pass with a...
