Q3: Are OOB (Out of Band or non coordinated) motors required with the WarpRunner and ESS?Ī: Out of band motors are only required for the way Mach4 handles Height Control, without the ESS. This process loop the repeats continuously. The ESS responds to the commanded velocity and makes the Z axis move and then reports the Z positions back to Mach4. On/Off button, Arc Okay, and all the other Anti Dive modes) then the WarpRunner will compare the current tip voltage to the target tip voltage 2'500 times per second and command a Z axis velocity up or down to get the two voltages to match. If Height Control is allowed ( by the H.C. Q2: How does the WarpRunner and ESS perform Height Control?Ī:The WarpRunner measures the current (actual) tip voltage over 187'000 times every second and filters that data down to about 2'500 data points per second. Please just believe us and use Mach4 and SheetCam. Other than this documentation, we won't support Mach3 with the WarpRunner.These features are not available in Mach3. This will eliminate may many crashes and save you lots of frustration and material. SheetCam has a post processor written for it, that takes advantage of all of the Anti Dive features provided by the WarpRunner.For Mach3 is partiality inside the SmoothStepper and partially inside of Mach3 where things can go wrong. Mach4 had all of the Height Control written from the ground up inside of the SmoothStepper and its plugin.If something is going wrong Mach4 will report what is going wrong, Mach3 won't.If you value your time whatsoever, and you want to avoid frustration, use Mach4 and don't use Mach3.
My problem is I didn't want it to flex the material, ever, whatsoever - which means I had to probe slower and have a fast response time - not only to avoid inaccurate height readings - but when using it to set the height on router bits (especially when touching off on hard flat material with no flex) there is much less margin for error - it just has to stop immediately and not run past the contact point whatsoever - (in routing circuit boards and things) I regularly use really small carbide tools like. In the first vid around 52 seconds in I notice it does flex the material a little bit - which makes me wonder if you're probing too fast and/or what the sensor response time is That's very interesting - I would have never even thought that an inexpensive off the shelf liquid level sensor would work for initial height sensing I love it - all that slag on your slats your machine must have more miles than my car - I've yet to cut one whole sheet of steel in total It's a fairly simple op amp circuit - I'm out of time to explain how it works at the moment It shows 12 volts but I think it should work with almost any reasonable DC voltage - if you use a higher voltage then eliminate or replace TVS-18V transient voltage supressor accordingly (that componenet isn't necessary)- maybe increase R5, R8 and R9 for 24V U2 is one half of an optoisolator - the other half (not shown) couples the probe signal to the BOB - the optocoupler and LEDs are optional but recommended I use a water table and water drops don't really collect on the probe or puddle under it (thanks to air post flow) - but it would detect on a water drop and of course that would not be accurate or useful - I haven't had any problems with that lately - but during development on a breadboard it was obvious that water, moisture and dust (even fog) can easily interfere with sensitivity adjusment and stability and detection reliability in such a circuit
#Sheetcam g31 skin#
I usually adjust sensitivity (via R7) to just detect my skin when I'm grounded - that seems to be a good setting - any more sensitive and it can false detect through moisture or dust - especially moisture or dust on the circuit board itself - my prototype is sealed in solid plastic The probe runs through normally closed contacts of the same relay that turns the torch on - so that the probe is not connected to the circuit when the torch (or spindle) is on The ohmic probe is represented as a resistor but of course it's actually an isolated touch plate that detects ground contact No - the weather has been so nice - I could just stay outside 24-7 -Ībout all I have ready is the circuit diagram - and a photo of the prototype
