Hey Guys,

I have been running a Hypertherm machine torch and consumables ($$$) for a while, and recently purchased a Yeswelder CUT55DS-pro to try out on my miniature DIY CNC plasma cutter. It is...

Thought I would share this with you all. It's tiny. I call it the worlds smallest production CNC plasma cutter. It works perfectly for my needs because my largest cut requirement fits in a 4" by...

No reason at all you can't keep using Mach3. You might want to upgrade the control board to a smoothstepper though. I had lots of issues with direct parallel port control because timing variations...

I have a set of two beautiful 5/8 (.625") Thomson hardened steel rails 3 feet long. They would normally use the SPB10-opn linear bearings, which are quite expensive. I have found 16mm open...

Through the wood and into the clouds..

Too rich for me. I'll stick to using my CNC mill for metals. What would be really interesting would be if a water jet like this could use table salt as the medium or some other graded sand to be...

I saw the video on YouTube and then came here for more information. Surprised that I haven't seen more discussion. Nice detail on how to modify the pump. Nice he can buy the ruby insert, but...

Thanks guys. The milling isn't "killing" me, I spend about four hours a month on it, but as I sit there making chips I'm always thinking of faster ways to do it. I do have an old Roper #92 10 Ton...

I have apparently been lied to. I went to visit a Hypertherm dealer today and he told me there is NO WAY to get that level of precision from any plasma cutter. My smallest holes are 1/8" diameter...

I do see where that could be nice, but I think that takes me too far to the other end of the spectrum. High speed mass production, where I only go through 1000 plates per year. My machine would sit...

I'm sure you all see hundreds of requests every year by people who think they want to build something and never do. I hope to NOT be "that guy". I have built a nice 2kW CNC mill and a CNC 40W CO2...

The supply you have is fine. Pwm changes the power because there is an rc circuit inside the supply. Note this is slow though. You will set a constant power level and then toun laser on and off...

Bart,

There was a time that I thought vibrational dampers were needed. Now that I have switched to 32bit DSP digital stepper drivers, vibrational resonances simply do not exist. I would have...

Lasermax10,

Any chance of putting these products up on Ebay in the USA?
They look very nice.

I find it funny that some are so concerned about the dangers of the 20 psi charged water filter that is "mostly" full of liquid anyway, but no one raises an eyebrow when someone mentions welding on...

5V on the supply is an output from the supply that is intended to go to a potentiometer and then get fed back as the IN for adjusting power level. Since the DSP puts out PWM, you don't use the 5V...

Here is the schematic I created to help out Marco at LightObject.com. He should be posting it soon into the manuals zip file.

He is sending me one of his newer stepper cards so I can create a...

As promised, I am updating this thread. I finally got the controller running with a little help from Marco at LightObject.com. This thing is GREAT!

Here is the video of the controller in action:...

Here is your answer. It is $475 and you will also need a stepper driver that can do 1/16 or higher microsteps (depending on your belt/motor resolution). This thing is way superior to the Link...

Hello all,

Just wanted to let you know that I found the fix for my machine that came with MoshiDraw. It is a DSP controller from LightObject.com It is a bit of an investment, but the end...

Another thing worth mentioning to anyone else considering a move to a closed loop cooling system like the CPU cooler. It is vital that the system contain a reservoir section and cap with a small...

Well this is interesting (or not), I just scanned the internet and found that most documents I could find were showing water flow in the direction of output coupler to high reflector. This is the...

I finally got fed up with the Mach3 game and just purchased this:

It is sitting...

buildlog.net has some good cutting edge info for laser engravers/cutters

I didn't know this could happen. I am nearing completion of a modification to my M40 laser where I have used a CPU pump and heat exchanger. Flow rate is about 1/2 gallon per minute. The heat...

If you go over to buildlog.net you will find photos and a very good drawing of the nozzle and just about anything else you would need for building a cnc laser. The forum over there is growing and is...

Thanks. That does look like something to try once I repair my machine. I did learn an interesting tidbit about high step rates and Mach 3 laser pulsing plugin if anyone is interested.
...

It wasn't so much adverse behaviour, but no behaviour. The command seemed to be ignored. I know very little about gcode and EMC2. No matter how small a program I load, the list of active codes...

Not yet. I got side tracked with the LinkMotion attempt. I will still contact the list and work to get a gcode solution. The laser/impact engraver plugin for Mach 3 works well for me, but Gcode...

Well after a couple days of testing, here is what I've learned.

1. G64 Px.xxx isn't doing the trick for me.

2. I downloaded and tested the LinkMotion virtual CO2 printer software. I could...
