update: just noticed that when I operate the X axis manually, quite often, before going to the right, it will kick a few mm to the left, then start going to the right ...

Hey Folks,

I've been running my 3040 CNC for years without any major problems.

Lately, I've had to change the stepper driver, as one of the embedded one went bad. I used some TB6600. While...

Hi tjb1,

The machine torch that I have seem to have only a trigger switch. I have searched a bit and did not find that it has any other form of control. This being said, monitoring the arc does...

Hi folks,

First, a little bit about my CNC/Plasma experience. I have already built 2 CNC, which are using the cheap chinese parallel port. I'm also using Mach3 as the operating software. So far...

The controller is an Arduino. All it does, is FWD/REV, with the speed being controlled by the reading of a potentiometer's value.

The principle is extremely simple: it controls a rotating...

Gerry,

Correct me if I'm wrong, but if I'm using 1/2 steps, it means I must "send" 400 pulses for a complete rotation. If I want, let's say obtain 400 RPM, it means I must send 160K pulse/minute....

that's because I already bought the motor and Power supply. Motor flange has been machined, and then we realised that the max speed, is not fast enough.

Application is not so much about using the...

Hey folks !

I need to drive a NEMA34 stepper motor, and so far, all the drivers that I have found, requires 400 pulse per revolution (Micro-step = 2). Why is that so ?

I need a model that would...

Hey Folks,

A little while back, I have built a wall saw, using some CNC rails.

Turned out I did not used it as much as I thought I would, so I have dismantled it.

So now, I have these rails...

Hi Folks,

I'm currently shopping to get a small milling machine. I won't need to create big pieces: it should mostly be in the 8"x5" range, mostly aluminum or brass.

I will definitely convert...

Hi Folks,

I have an M700 Redsail Laser cutter.

So far, I have been very disappointed and I'm wondering if it could be possible to remove the actual "control Boards" and replace them with...

IMO stay away from that company: I bought a M700 a year ago, and I have had nothing but problem with it. Right now, it's no longer working, and nobody is getting back to me from Redsail, to help me...

Back a couple of months ago, tech support was horrible, now it's literally nonexistent.

Hi Everyone,

re-aligned everything...not much difference....

look at this picture:

Service is HORRIBLE.

If I had to do it again I would NOT buy a Red Sail....

Regarding the ammeter, for a 80 W tube, at 100%, what value should I be reading ?!?

Just out of curiosity, what voltage level is present at the tube ?

there is no ammeter installed on my machine.

What type of ammeter are you talking about, where in the circuit, should I install it ?

Hi Everyone,

A little while ago, I bought a RedSail laser cutter, M700, with 80 Watt tube.

When I first got it, I was able to cut 1/8" Baltic birch plywood, at about 50mm/sec with 60%...

4th day without any answer from Red Sail ...

Happy-customer-o-meter going down !!!

Exit of the laser tube is clear, mirror and lens seems clean....

what puzzle me is the fact that over time (30 minutes, tube NOT continuously 'ON') the power required to cut the same...

the cuts are made within a few minutes from each other: beam alignment/cleanness is the same...results should be the same !

I'm seeing some kind of decay once the machine is 'ON'...I mean by that,...

Hi Everyone,

little follow up: Communication with Red Sail is getting slower and slower !!!

I'm slowly...

I mentioned that it can be freezing here....

I was hoping for a comment/advise with more ...meat !!!

Hi !

What you you guys using to cool your tube ?

I read a few things about using Propylene Glycol.

Since it's freezing where I live, I was thinking about switching from Distilled water to...

Hi Everyone,

Has anyone used their LASER cutter/engraver to do lamacoid ?

I'm just curious about the fumes: are they extremely toxic and/or corrosive ?

I understand that all fumes are...

Hi everyone,

I just received my Laser cutter/engraver, and I would like to share my experience, as some members requested that in the past.

It is a RedSail, M700 with an upgraded 80 W tube. It...

Hi Everyone,

I'm building my own CNC and I have a problem. First let me describe a little bit the installation:

the CNC will consist of 4 motors. All the motors are the same, that is:

Hi Everyone,

Hi Everyone,

I currently have a small Chinese CNC (model 3040) and I'm in a process of building a bigger one.

I came with that (stupid?) idea of putting a LASER of it, in addition of a router....
