Thanks for sharing your knowledge guys. I think you're right that the best way forward is to spiral mill the holes & work on deep pocket chip removal.

Thanks for sharing your knowledge guys. I think you're right that the best way forward is to spiral mill the holes & work on deep pocket chip removal.
I need to drill 7/16" diameter x 2" deep holes in 6061-T6 aluminum. Making 50+ parts, 9 holes each. Problem is my cnc router doesn't have low-rpm torque. How do people with high-speed spindles...
Sorry to resurrect an old sleeping thread but I can't find anything on how to implement this 'wait for spindle up to speed' feature.
Is this a Mach3 feature I haven't run across yet?
Or after...
Apologies for the delay.
Regarding, power requirements. To clarify: This is a 5.5KW VFD driving a supposedly 3.2KW spindle motor, although spindle markings indicate the original was 8A and the...
[Quick update, after some experimentation I've found that a 2k pull-up resistor seems to be a good value to use. It pulls about 5mA open-circuit and about 12mA when the probe touches. This appears...
Thanks!
One thing I should've mentioned is that I've had electrical noise issues with this machine, especially on the probe line since it floats. This has been creating false probe touch events...
I don't understand how to hook up the probe circuit.
My understanding is that the power supply neutral (24V0) is supposed to be isolated from machine ground. Is this correct?
If so, how do I wire...
This is 1-phase 220-240VAC power into the Fuling DZB312B005.5L2DK VFD that's rated for 5.5KW. There's a 30A+30A breaker at the mains, ~60' 10-Gauge cable to a NXBLE-32 32A breaker on the machine.
...
That's a good idea but no the motor is clearly labeled 220V. Specifically, the old spindle is labeled:
HONG YANG
NYM110-24Z/3.2 *note: this spindle is marked as NYM110 but careful measurement...
Ok, I'm beginning to understand the situation better. It appears that the Alibaba spindle vendor, who is supposedly the manufacturer, shipped me a mis-labeled sub-par replacement. And over-billed...
I received a further clarification from fuling:

Dear XXXXX,
Regarding your first question, I want to answer you, our DZB series use open loop V-F control, you only need to set the motor...
Thanks for the reply @mactec54. Actually I reached out to Folinn (aka Fuling) and they had a rather odd response. Unfortunately the answer isn't as clear as we'd like. So now I'm even more confused...
F1.01 thru F1.05 are correctly set. Is there a parameter I'm missing??
I've been having various problems my Fuling DZB312B005.5L2DK VFD after replacing the spindle. Symptoms include reduced performance (bogging at moderate loads), over-voltage alarms on stop braking. ...
After suffering a bad manufacturer-configuration related crash, I decided to basically re-engineer the machine after discovering too many problems everywhere I looked.
For alarms I decided to go...
I'm trying to understand how to properly connect a CNCdrive AXBB-E controller to Delta ASDA-B2 servo drivers.
Background:
1. This machine (AlphaCNC AMN-6040-M) came pre-configured with an XHC...
Hi LVz, Thanks for the suggestions! I had to back-burner this due to time issues but will look closely at your parameter suggestions ASAP.
@mactec54, apologies for the lack of reply; I had...
Thanks for the attempts to help, guys. However it's still unclear to me how to proceed.
@mactec54, you're saying to connect the braking resistor to the DC+ & DC- terminals, correct? I'm...
Thanks for taking a look, mactec54.
On one hand, it seems you're right - this is what the manual seems to indicate in some places. Considering where it's from, in some ways the Fuling DZB series...
The VFD is a FULING INVERTER DZB Series DZB312B005.5L2DK. The Braking Resistor is connected to DC+ and BR-. Powered-off, resistance at the DC+ BR- terminals on the VFD with the braking resistor...
Thanks for responding, mactec54. You clearly know far more than I do about the electronics side of things. Probably all sides since I'm pretty new to the realm.
Happy to oblige :)
Anything I can do to assist, just ask.
I just ran thru and wrote down all the VFD settings and am transcribing that to a file. If that might help I'm happy to upload that...
Quick update on voltage readings. Think it's DC after all. Reading 0.00VDC across brake resistor while running and braking.
Hi DMoore,
Thanks for posting about this. I have the exact same VFD and am attempting this breaking resistor install.
But I'm having a problem - it's having no effect. Apologies for...
This is residential, so 220V 1-phase, wired direct to service breaker box via over-spec wire, don't recall exact gauge at the moment. Two breakers, one at service box & one on machine.
Since it's...
Thanks for offering to help!
The VDF is a FULING INVERTER DZB300 series. Specifically, markings are "DZB312B005.5L2DK". The inverter drives a 3.2 KW spindle motor. If you can, can you pass...
Fair & well said. I agree with your assessment, this is why I chose the machine. It could do what I needed at a cost I could afford.
I'm going to do a mini-brain dump here, hope you don't mind....
Thanks again for the feedback. Maybe I'm getting over-concerned about the bearing noises? Being a n00b sucks, so much to learn, so many mistakes to make.
And yeah, sorry for the confusing...
Thanks for the feedback guys.
Just wondering, does anyone know what Mach-3 internally does on REF ALL HOME? Since that works correctly, if I understood what it's doing maybe I could figure out...
I'm new to g-code, so apologies in advance if this is a dumb question:
I'm trying to improve my machine warmup program. Currently it just ramps up & down the spindle a few times. I'd like to...
