Try with brake cleaner, and add light oil to prevent rust.

Verify the emergency stop circuit and all safety device on your machine.

When an emergency condition occur, the controller disable all axis and show you alarm 401.

It's appear to be an e-stop problem.

Have you try just pushing your e-stop.
You can also try inverting your e-stop in config, input pin.

Don't forget to try your e-stop after that.

reinstall software & driver. Check your setting of the parallel port. Make sure you don't have a software in background that can try to access to parallel port. It also can be your video card driver....

By using rotating-nut, you can go faster without need of using huge screw or support bearing.

ROTATING-NUT. The lead-screw don't turn so no whip is possible.

I hope you don't think to make production with a 3.5kW spindle.

Normaly electronic can support 50 and 60 Hz. The main problem is with motor. At 60 Hz, motor run faster and the current drawn by the...

By measuring the width, lenght (and number of tooth) and pitch. With this info, a salemen can found the belt you need.

Yan

In any industrial part supplier. Just take the part number on the belt.

You can start by adding a booster in-line with your dust collector. (the booster or blower should be near of your machine)

Air blast can also help you

You also can add a capture hood near of...

You can try slower baud rate. And verify if your baud rate, parity, stop bits and data bits match the cnc controler.

I have the same problem on my Routron, at 600 baud everything is ok. At higher...

My bad, it's not the white is the red.
All OK and doublecheck with a voltmeter if you have 5Vdc between +5vdc and -5vdc.

It's also a good idea to verify the polarity with a voltmeter BEFORE to plug any wire. Reverse polarity can destroy the switch.

Yan

You can use resistor 1/4 watt, standart.

The resistor must be in-line, you can destroy the led if you plug 5v directly to the white wire.

The 0volt is the common of your +5volt. I don't know...

I found a good model for you.

Or if you want bigger:...

I also need the polarity of your input. If your common is - or +.

Yan

The switch are NC. You need to add one wire to supply the led. You will need to add a resistor for controling the current through the led. And another resistor between the output transistor and...

Yes, my switch are similar. The first part of the switch is a infrared led. The second part is a photo-transistor. When the transistor "see" the light, the current can pass and when it dark, the...

With large amount of dust (on the photo-sensor), the switch will not work. Clean it with a air blast and you have a brand new switch. So it's a good practice to clean the switch when you clean your...

In response to Cartierusm

An optical switch will ALWAYS send their signal at the same position. A very accurate snap action switch will make the job but, maybe 6 month later, you will notice a...

It can be the memory or cpu, if Rally can't help you.

Yan

For homing, i use optical switch and fixed speed. The switch is NTE3100 (or ECG3100) with little experience in electronic, you have a very accurate home switch under 10$.

At my job, our machine...

check for a broken wire, accelaration parameter, Volt curve (Volt VS RPM) (I have see too low volt at low rpm with the same symptom), spindle feedback (and all signal coming from spindle), signal or...

If you put neutral on L3/N and 120V on L1, try 120V on L3 and 120V on L1. It must be two different wire. Probably one RED and one BLACK. You can measure with a voltmeter and you must have 220V.
...

The VFD take your AC power, convert it in DC and then make AC 3phase.
To convert in DC, it use a bridge of diode. So even if you invert L1 L2 L3, your drive will run. If you put the power on the...

Check the website of centroid. (if the mill you want is controlled by centroid)

I have build a router and my screw have a pitch of 20 thread per inch (direct drive). With this setup, my resolution is 0.000025 inch per microstep (10 per step). This is too accurate and my feedrate...

The cnc is a Routron rtr from SCM. The communication software is Tooling, from SCM. My problem: I can not transfer entire program to the controller. It accept only between 60 and 75 lines and it...

If you want to keep the original performance of your motor, don't use Gecko drive, because it run at max 80Vdc. The motor will have less speed and stall torque.
