The KBIC is NOT isolated from the mains, there is NO transformer inside of it. There is no need for it to be and it would just add to the cost to do so. Since they have made them for 25 years or so I

So I went a little further in the configuration(set up my pins/signals in the ESS), shut down and reran Mach4, and now, when I attempt to get back into the ESS Plugin configuration, it highlights the

i checked the manual for my KBIC speed control and it is clear that what you describe is the case. i also measured from the pot to ground (earth) and was shocked to find just what you describe. the

Using win 7, Mach3 Turn, gecko g540 and uc100 Just starting to use Turn and ran into something I don’t understand (there’s a lot I don’t understand). When I issue a G03 command it seems to

Sounds good, will buy the DC-03 when i decide i need program control. need to get the motor working first and determine if i can get a better finish by varying the speed for different cuts. i am

Read up on what reference voltage is. (Or read Peter’s post again – he tells you.) Sent: Wednesday, 11 March 2015 4:32 PM To: mach1mach2cnc@... Subject: RE: [mach1mach2cnc] VFD and PWM

Thank you Andy! That was a real help for us, Steve worked on your issue for 8 hours! it was that hard to find and I think he did one heck of a job to find it that quickly! This should help many users,

Hey you can do as many great things as you like but its support is getting to be limited and we picked what worked best for us.Mach4 is cross platform and so is Lua. Everyone that has taken the time

No I don't think I was over the top. If you use a multimeter to measure the voltage across the manual speed potentiometer of a KBIC-120 controller you will get a reading around 10-15V. Touch the wire

Hi Spencer, One or both relays on the DC-03 can be controlled separately from the spindle control if desired. In normal use they are controlled via the M3 and M4 commands on the Mach3 spindle setup

i read the manual for the DC-03V3 and it all makes sense pretty much. it looks like this will be a better solution to using an FET board because it must have some time integration that would be

Peter: Did you just go over the top 10 volt DC will kill you. The pin our isolated (7&9) on 540 as we know it. I let you know if I blow something up Good trying C Sent: Tuesday, March 10, 2015 9:49 PM

Hi Spencer, Most VFDs accpt a control coltage in the 0-10V range and supply a 10v power supply for powering a conversion circuit. It is prudent to put an opto-isolater to isolate this supply from your

Hi, Without exception (from my experience to date ) all VFD's have a 10Vdc supply that is used as a power supply for attaching a manual speed potentiometer. This 10V supply is used to provide power to

Brian and Steve spent some time on my PC with a remote connection yesterday, and were able to solve the problem by making changes in Mach4. Brian did mention that this PC is at the low end of what is

Mach3 can be set up to generate PWM on any pin that you like. This is done with the dialog at Config > Ports and Pins > Motor Outputs. Fill in the desired PWM pin under Step for the Spindle Motor.

i read it all but it is for an air cooled spindle and the most important point relates only to air cooled fans etc. mine is water cooled so i don't have to worry about that aspect. i assume you run

Almost all of my g-code is created using a VBA macro in AutoCAD. VBA's not dead, or going away. Gerry

Start out by saying i don't consider myself even near the same league as Brian, Art or the others that program. Just a mere hack. Like yourself I have used VBA although in the DOS days was doing LISP.

Excellent, what type of power supply can I use for this as it appears a second power supply is required Thanks Chris
