Router with template will make short work of often needed holes, whatever shape. Useful if you often need to make the same size/shape hole.

The reason you need less than the combined max current for your power supply:
The stepper is rated at its operating current at a much lower voltage that the voltage of the power supply you will be...

Hi

Perfectly possible, I have been running a router as spindle for several years now. There is not that much you can take off the machine to use it as spindle: what you see is basically the...

Laptops = BIG NONO!

Most posts on the zone agree on one thing: trying to run from a laptop causes no end of problems for a wide variety of reasons. Best stay away from them.
(for linux and for...

I have been using linuxcnc for some years now. I do not have programming experience so you got a head start right there! The process of getting linuxcnc installed is really simple: as previous...

One trick I used for my workshop drawers: use 3 pieces of square hardwood profile, say 10 or 15mm square. One piece goes on the drawer side. The other two go on the frame and form a channel for the...

I use a 1/2 inch to ER20 adaptor with a set of ER20 collets. This allows you to chuck anything up to 13mm in your router. I did have to make a new collet for my router to get a decent runout on the...

Looking at your spec: 6.1A at 3.4Volts=21Watts. So why would you need a 1000VA for 3 or even 4 of these?

What has been overlooked: the stepper driver acts as a dc-dc converter: making a high...

From my experience, emc drops pulses immediately and also the enable pin to the drives. No rampdown.
I would advise against this being your main way to do an emergency stop: if the reason for the...

I can do it straight from emc startup, without resetting e-stop or power?
I just click on the line: it changes to highlight, right-click and there is the option: Run from here.
I have attached a...

Simply highlight the line of code where you want to continue and rightclick: you will get the option "Run from here"....

The small voltage difference is not a problem. The current specification will be the limiting factor. Too high a current will heat up the connection and cause contact overheating. If your contacts...

Thank you Danny!!!

A great resource, many thanks for making it available for all of us.

Hi Mechstew,

I have been down the same path: got working webcam but no software to make use of it!
It would be great if you could share your solution!

Alex

Nice one, thanks for the files, they'll come in handy!

Hi Mervin

Looks like your driver board is more than capable of doing what you want. A bit more drive voltage will help as it will allow higher speeds.
Apart from the obvious concerns about all...

Hi Mervin
Control via the parrallel port is perfectly possible, thousands of people are doing just that on this forum either via dos/windows or via linux.
For instance I run a machine using drivers...

Hi,

The UK arrangement for a home supply is normally a single phase, 240V. The generated power is always three phase, they just divide the streets up between the three phases in the substation to...

Thanks Mike

Just what I was looking for!

Shoot-through is a very likely cause.
The diodes you refer to being used on standard motor circuits cannot be used on a stepper as you are reversing the polarity while stepping. The usual protection...

I have used them in cable tv networks. These are usually either 60 or 90Vac output. They have the benefit of stabilising variations in load and input voltage, often up to +-10 percent.
Current...

Did you have a look at VNC (google..). It provides remote desktop operation on a multitude of different platforms and once installed will run/control anything that is running on your machine. (no...

You have 19 Volts accross the regulator times the current consumed by the following circuits= power = heat production!
Do you have any cooling fin on the regulator?
