This is an old thread but in the end I purchased a Thermwood C53 and its great. It still runs no problem with modern cam programs. The only bug bear is the lack of file transfer other than a 1.4mb...

Hello yes over the last couple of weeks I have rebuilt the machine. It is currently a litttle further on than what you see in the pictures. It is now made from a steel base onto which I am mounting...

The z - axis is sometimes moved with the laser head.

The larger 2.4m by 1.2m machines have the laser mounted on the gantry and use ball screws to move the gantry around. If you don't need the size...

Today I removed and cleaned the motherboard, RAM and disk on module and now everthing appears to be just fine. Hope I can get a few more years out of her yet before she needs a conversion.

Thanks...

Yeah I think it looks like a great mill for repairs and prototyping. I bought it mainly to make parts for my cnc router and have ideas of making small injection mold tools.

I have hooked up a lcd...

Hello, I have bought a 2001 ez trak 3 axis cnc knee mill. When I viewed the machine everything appear to work fine but now I have it home I cannot get the computer to load. The display has only...

Thanks Davy, I have been using G804 for the last couple of weeks and while it works well on most corners there were still times when it would not slow down at all for a 90 degree turn. I will try...

I have a 1997 thermwood c53 3 axis router. I have been getting to know the machine and have been running it at slow feedrates, now its time to speed things up and for some real cutting.

My...

Hello I am looking at buying an Emco mill 50 . I would like to know an accurate measure of the Y axis travel, there seems to be a lot of variation online from 90mm up to 140mm?

Many thanks

Hi it looks like you got a nice finish in the aluminium. How did you find using the small end mills, was the spindle speed a limiting factor. What is your spindle max speed.

Cheers

I have been trying to do a basic copper plate using Copper sulphate (Copper permanganate).

The main issue I am having is the copper is plating onto the steel without any current at all being...

Wow nice job!

Ha ha looks like a lot of folk have the same idea. I also phoned the chap selling this machine to enquire about replacing the laser with a chinese glass equivelent. Refurb costs are high (£2000) and...

I like the way you managed to use a cnc router thats largest axis is smaller than the workpiece being machined.

Are you using a truss rod or carbon fibre renforcement, I guess if you are using a...

This is part of the enclosure containing the electronics like the drives, Pokeys and Kflop.

Birch plywood top, routed to take buttons and switches. There was a lot of tearout doing this which is a shame.

Made a little breakout board to help wire things up for...

Mainly out of interest, I have a sloppy machine that is giving errors of 0.2mm and above. I would like to get the mechanicals better before running in closed loop.

Plotting postional error while running code in mach?

Would it be possible to use Kflop to output the postional error while running some gcode in mach or KmotionCNC.

The motors would be steppers...

So Single ended and Differential signals will give you the same resoultion as each other but differential signals will be more robust/less effected by noise?

Gav

Thanks Tk,

Is it possible to make use of quadrature encoders with just the Kflop or do you need the kanalog expansion board to make use of the quadrature feature?

Cheers

Gav

Just to clarify I am talking about closing the loop with Kflop, not adding a DRO to mach

I im thinking of using glass linear scales with my router that uses stepper motors

Do I need to be worried about matching the resolution of my scale with my steps per mm of my stepper and...

Hi Al, I think so. The laptop is a couple of years old. On one side of the machine are two usb ports that look standard on the other is one extra port with a lightning bolt next to it I assume this...

Need a little help with the first hurdle.

Trying to install kflop drivers on a vista 64 bit laptop. I keep getting a failure notice once the driver installs. In the device manager I can see the...

Hi,

I have a small A3 sized router from marchant dice in the UK. It has been great for prototyping small parts and I am happy with most aspects of the machine.

It does have one majour fault in...

I have been thinking about how best to machine both sides of a guitar neck.

Are there any good resources out there that deals with neck machining?

Im thinking its a case of jigs and location...

I have ordered a Kflop which should be here in the next couple of days. After I have finished up a few paying jobs on my router I will have an opertunity to change from parallel port to kflop.
...

Im happy to use Kflop for the MPG.

Will the MPG work with a open loop system or does it need encoders?

I am thinking about getting a kflop to generate the pulses for my stepper motors. I am currently using an old sony laptop with a parallel port for all my machines. The laptop appears to work fine but...
