Any of these reverse the rotation? I'm running counter clockwise and I want conventional. Maybe this? P00.16 = 1 ; 1= REV(X6) Determine direction:Open Yes FWD,Shut Yes REV;FWD(X5)Start command:FWD Stop,REV Boot
Any reason this would remove torque? It's spinning clockwise now but bogs down and blows breaker. Same feeds and speeds I've always used.
I had it right to begin with. Clockwise looking down the barrel, not head on. Been a while since I've fired up the cnc, I sure do miss it. Thanks for the help.
These settings are for the VFD itself, nothing to do with a specific controller? I'm switching from Blackbox to AXBB-E. Hoping I'll just need to connect 0-10v signal and be done.
Should be able to. Never came across a VFD that couldn't be configured properly to just need 0-10v signal yet
I have done the above wiring and setup, with BBX32 and YL620 VFD. It works. Thanks!! I can change the rpm with OB Control tool menu. However, it isn't picking up the rpm off the gcode file (ie - it is always at 24K rpm) I have to adjust manually. Does OB controller not pick this up from the gcode file? Thanks.
CONTROL just sends your gcode over to the controller (; Did you remember to set $30=24000 in your firmware settings? Grbl v1.1 Configuration
Peter - thanks for the quick reply. However, I think I should have worded my post a little better, apologies. I will try again and with new findings. When I use OB Control GUI I can control the speed of the spindle with the 100%, 75% etc drop down. I was excited thinking this would roll over to using Gcode. It doesn't. I had not set $30 to 24000, so I did, the spindle would not come on with the GUI as above. I dropped back to $30=1000 the VFD shows around 385ish HZ(it fluctuates some). and the spindle seems to be spinning at 24000 (by sound). So I tried upping $30 in increments: 1100, 1200, 1500.. The higher I went the slower rpms on the spindle until finally it would not spin. So that seems to be problem #1? The initial reason for this post is that when I load a Gcode toolpath the spindle rpm (and VFD display) does not change to the setting created by Vcarve tool database. The VFD shows 385ish no matter what tool. I can't change the VFD freq manually since I have it set to take the frequency from the controller. I was hoping the rpm and feed/speed would be automatic. BTW - I have configured the VFD per the YL620 post in the docs for Control. I hope this makes sense, trying to give you all pertinent information.
The menu is aware of the current settings and can scale whatever it should be to suit. Your Gcode coming in from outside - does not. After a major change like that, you would have to refresh your Grbl Settings for the menu to know that it now needs to have a new range to respond to, or a disconnect/reconnect at least. Always after major changes to settings, restart things to start fresh and aware of new settings Set it to $30=24000 - thats what your spindle's 100% speed is. That value is just for your readability so you can put RPM=24000 into CAM workflows and the firmware knows M3S24000 = 100%. 100% = PWM set to 100% duty. 100% duty into PWM to 0-10v converter = 10v going to spindle. VFD knows 10v = 400hz. 400hz with three phases and a 4 pole motor = 24000 rpm. Or if you put RPM=12000 into CAM workflows and the firmware knows M3S12000 = 50% (because $30=24000, 12000 must mean half). 50% = PWM set to 50% duty. 50% duty into PWM to 0-10v converter = 5v going to spindle. VFD knows 5v = 200hz. 200hz with three phases and a 4 pole motor = 12000 rpm. Exactly, if you have $30=1000 - then M3S1000 is 100%. But M3S12000 is also 100%, M3S24000, is 100% - M3Sany-value-over-1000-which-is-your-$30-setting is 100%... (As explained in the Grbl Wiki i linked you to, it can only go to 100%, so values between min and max scale, values over max just = max) 385 vs 400hz difference means you probably skipped the 0-10v calibration but 385 = 100% in that scenario. Set things how they SHOULD be, then restart it all so its fresh before you test
RESULTS! I must have been in a hurry when I did the initial setup on calibrating the 0-10v. I redid it and now I see 400 on the VFD at 100%. I shut down everything including rebooting the laptop and now I see the gcode setting the rpm on the job. Thanks Peter!!
