OKay…. I might have jumped the gun on this one. I think when I saw Mary's post I thought "Hey that's happening to me". On further inspection there is significant wobble on the table, I need to adjust my gibs. I think that's the problem because the further out on the corner I go the bigger ...

Good idea, I’ll cut air. I’m also going to try cutting the circular pockets using intercon (I usually use fusion 360) Not random, 4 other circular pockets for a different project with same result - stuttered in the same are. I’ll upload my wiring pic (although it’s a mess) and report back with above...

Okay, I'm going to hijack this thread since CNCMaryland is not responding. I'v attached the report File; report_985DADB4AC90-0929170136_2019-06-25_19-16-00.zip I have a G0704 conversion with DMM DYN2 drivers and 400wx2 DMM AC servos and 750wx1 DMM ac Servo on Z axis. Wired according to Centroid sche...

Same here- just started recently. I notice it in a circular tool path when climb cutting at around 10-11 o'clock, when I speed up the machine then I start to notice it a little at 5 o'clock as well. Checked my 'lash and it was the same as when everything was working well. I checked on here to see if...

Thanks for the reply. The z axis was one of my concerns, I Didn't realize there was a brake option. My head definitely drifts, I am not sure what the holding torque for for 750W servo is but a brake makes sense.

Hi everyone, I have a small G0704/BF20 Mill currently running acorn with steppers. I just placed an order from DMM for 3 DYN2 drives, 2 NEMA23s 400w servos (57N-DHT-A6TD1) and 1 NEMA 34 750w servo (86N-DHT-A6MD1). I asked the gentle man helping with my DMM order if I need a belt reduction drive for ...

Thank you both! You guys are great. It is almost certainly the column out of tram. I had a small crash a few weeks ago and I remember thinking about how I did not us a torque wrench when I installed the column on my cnc conversion and maybe not tightening the column bolts as much as I should have. I...

You should not have guaranteed :) I programmed it in intercon and it looks the same. Picture attached (top is with fusion 360 post and bottom is with intercon). intercon Gcode attached. I've also attached a drawing of the test drilled hole with counterbore (circular pocket) and measurements. The too...

Hi all, I was wondering if anyone had this problem or could help- I drilled a hole with a 5/16" drill bit (fusion 360), then 2D adaptive to counterbore it with 3/16" end-mill. The drilled hole was supposed to be centered in the counterbore as is seen in the pic of the Fusion360 simulation....

Just for my info why the G0678 over the precision Mathews - PM-940M with hardened ways?

I’m with you on the small frame and travel of the bf-20s
