working great some minor crashes and bent tools!
I have used oven cleaner on a super gacked up old sheldon I bought
Not sure, check the driver and make sure it puts out enough current for the replacement. Why do you think the stepper is bad? Steppers are very simple and don't have many problems. you can measure...
not sure what can be done in this instance other than syncing the motors with a timing belt
please give more info , your control etc.
I only run at low speed for a very short time to edge find .Get within a thou, spindle never gets warm. I use this mainly when I put the vise on the router table and set a G55. I will look at the...
I have a 1.5kw air cooled spindle and I run at 2000 rpm no problem with a 3/8 edge finder
the ESS documentation states "The ESS relies on the breakout board for isolation " and "The ESS has drivers that are capable of driving opto-isolators directly" thru the 74ACT541 chip as john shows.
that can work that way it's called common anode and it may work common cathode . you can wire your breakout board to connect either way .Do you have a pic of the drive?
Mount your aluminum stock on the table anywhere, I will assume that x,y 0,0 is the bottom left corner of the toolpath you want to cut . Now you will move the cutter over your stock at the bottom...

Goemon in his original post stated he has a 7.5HP spindle. "My spindle is a 7.5hp 24,000rpm 3 phase unit. The label states 18 amps s1 although an online vendor lists it as 20.5amps"
7.5HP x 746=...
I was engraving some 3/8 plexi and it varies .010 in 12 inches measured in different places.
get your self an AC clamp meter, there not expensive and you will get some answers
And for Power supplies I use and like Mean Well. limit switches I use N/O cheap proximity sensors from ebay
I chose leadshine as they are a real brand. Their products are copied, cloned and sold on ebay , so far no issues, the drives appear to be well made, good documentation. the first drive I purchased...
275 IPM my power supply set at 52v
On my Benchtop PRO 2436 I used Leadhine 86HS45D and Leadhine MX4660
you should see 12.xx on the meter with red meter probe connected to brown and black meter probe connected to blue wires of the sensor . when the axis is off the home position and led lit you...
I would test with a meter to verify as that seems to be your original concern. I think on your bob both 12v neg and 5v neg are tied together. On boards that I use I keep them isolated
I mistakenly used the word ground . I meant the 12vdc negative and is called GND on bob.
connect n/o switches in parallel. Yes you are correct you just tell mach3 that you have limits using the same pins as the home switches, and A home switch on its own pin so you can square
its fine the input circuit will tolerate this as the sensor will sink current but not source current. Jim I assume that your sensor Black wire is connected to the bob input pin (12) is this the way...
I just made a test setup using an npn sensor and 24v it can only pass 2.3ma so its resistance is about 10k . crap, just blew the fuse again in my meter, seems like I do this all the time, forget to...
not all of the bobs are created equal, one Chinese mfg copies another and gets it wrong and they all look alike. but we buy em cause they look good and are cheap.Then you need to be able to reverse...
it can provide additional output and clean up the signal , it is a simple amplifier . it cannot isolate like an opto
it means your input signal connects to a buffer before it goes to the parallel port .non buffered means you connect directly you the parallel port. the buffer in your case is a the 74hxx chip which...
some of those ebay Chinese BOB's have opto inputs
that looks correct now, many of the proximity sensors wire this way. Brown to +V Blue to -V or Gnd. Black is the switched output
