Sorry - forgotten that bit! Trouble with following multiple threads over a period of time....

Looking back over the current problem, though, it is a bit odd if there is the same absolute error on...

And I've just had a look at the DMA860H manual! Yes, no fault output. One of the reasons I chose the EM806 was for this reason. So, looks like you will have to do without and just be a bit careful!...

On modern digital drives (I use EM806) there is a stall-detection capability. Typically, if a motor is stalled at above about 300rpm, the drive stops and enables the fault output signal. You can use...

It's easier to just drop power to the drivers so the motors can turn and just turn the screw by hand. I had a home switch on A as well as X and used that to do manual homing of the slave axis using...

It's easy to get too wound up about these things. Whether you should use 60%, 70%, or 80% really doesn't make a bit of difference - if you are using a linear (i.e. toroidal transformer, etc) anyway,...

Try this one.

It's not easy to find things like this when the last post to it is more than a week or two back - they just get lost in the noise!

In fact, it's about as easy as finding the...

Personal view here, but based on using my own machine for the last 2-3 years. It's described somewhere on this forum - search for "AVOR" and my username if you want to look it up. It's built mainly...

Isn't this just a question of wording? A misaligned Z axis will not cut square and will need tramming. When I say "misaligned", I mean not moving exactly vertically in either the left/right plane or...

As per Jazz's picture, you need a recess in both halves. As I remember (and I can't find a drawing of it to hand) the recess was wider somewhere around the middle of the plate to give space for the...

How about Prusa? Can't remember latest model number but good reputation. Save a bit building from a kit. Lots of cheaper clones around but the real Prusa gives you best chance of just "assemble and...

Sounds good to me. I'll step back and wait for the experts to comment!

Sounds like your "steps per unit" calculations have gone a bit wrong. Can you recheck, or post all relevant data here so someone else can check your working?

The other way of doing it is starting...

Under the 2D operations drop-down menu, I would use "Contour" for that. I'm assuming that you have already created a "setup" which defines the work coordinates? For something like this I would set...

The title comes from a regular feature of my model engineering club where members can show projects in progress or finished. I'm posting here because I made passing reference to one of my projects in...

The fact that the drives are rated at "20V-70V" AC in is a pretty clear indication that they are very tolerant of input voltage variations. The only thing that really worries them is input...

I think the answer's in the question! The best form of spotting drill is a spotting drill! Centre drills are intended for drilling holes in the end of a workpiece to take a lathe centre, hence the...

Frankly, what you call the axes doesn't really matter that much but you must obey the convention that the axes of the machine in front of you match the way that the axies fo conventional drawing...

If it's this pulse edge problem - certainly sounds like it! - then you can either swap over the "step" connections at one end (IP/M or driver) or change the "active high/low" setting for the step...

If you are going to run Windows 10 then you can't use the parallel port on any PC with Mach3, so you must use some kind of external motion control hardware. Something like UC100 is the most basic of...

Classic problems with Mach3 are getting the ports and pins set correctly and getting the motor tuning (speed and acceleration) set up. However, that's something that you will need to do with any...

GRBL is motion control software that runs on Arduino. It takes in gcode - think "move cutter to X=10, Y=25" coordinate-type instructions. It turns these into the pulses that the motors need to move...

I'm assuming that the machine will run off something like a dedicated 16A 240V single-phase supply? You probably won't be using the "variable frequency" feature anyway and would leave the VFD set to...

Looks to me as if there is a backplate as part of the package - the "2mm galvanised steel mounting panel" item. Does make it easier to get everything fixed before bolting into the cabinet.

Have...

I'd go along with the "it's never big enough" idea. Do a dummy layout of the bits going in there, work out what you need to house them, then go a size or two bigger. Otherwise, wiring the thing is...

I can't comment on the switch wire colours without a diagram in front of me, but you do need to take a wire from the -ve pin for your chosen input to the common negative - on the IP/M both sides of...
