I'll see if I can borrow a scope. Thanks all

@oliof Tested at 100,200,500. I see no significant difference. I removed the inverted ! in the M452 just for testing. At S245 HZ is stable. at S246 the HZ starts out momentarily at requested frequency but then varies between 60hz and requested. At S248 there is no HZ. With the ! inverter the Number is around 20 for the "S" The voltage does change with "S" changing. Full range. Does the Laser need the HZ? Has anyone else tested for HZ?

Unit is a Duet 2 wifi firmware 3.4.2.

I'm in experimental stage. With a Fluke 76 meter set to HZ I will read Frequency if my command line is G1 X50 S200 F100. If the "S" is set above 240 or below 15 I will read a voltage but no frequency. I have voltage readings all the time. Voltage varies "S". I have also test this on Bigtreetech BTT E3 RRF. The min and max numbers are little different but not by much. The output voltage can't see max if it's lower. I have not hooked up to laser yet and/or tried to create a file. Is this acceptable or is there a way to get full range frequency? Can laser application put limits on "S" range?

I figured it out. I added a I1 in the M558

Installing a Orion Piezo on a cubex. The Z probe is always at 1000 with or without piezo connected to probe header. When connected and i touch the end of the hot end the blue light flashes and Z probe goes to zero. in this configuration I get a error that the Z home signal is on before homing starts. I'm configuring this thru the RepRap configuration software. I've also have left the configuration to z probe and then used a n/c switch but it start to home but i can't stop it. the blue led flashes when I tap the hot end but it doesn't stop. The following moves x,y to 25mm z retracts (30mm?) and then I get the error. Thank You for your help. I'm about as new as one can get to this.
