Hi,
I have a Stepcraft-840 which is giving me trouble.
I tried to home the axes.

Y is homed ok.
After I home X, and try to run it at 50% speed to the end of the axis, just to see if it goes...

I tried going for the smaller bit diameter. It seemed to work much better. I'm not sure if it's perfect but going 4mm or less is definitely improving the process.

Thanks.

Okay, thanks! I'll try that.

I usually don't go too deep relative to the bit diameter because it already happened that the spindle couldn't handle it and was dragging really bad through the wood.
I think my machine rigidity is...

Hi,
Thanks for the reply.

I understand what you say about the compression bit pass depth, but I'm trying to achieve a relatively clean border edge. From my experience the upcut alone creates more...

Hi,
I'm using a 6mm diameter compression bit to mill a 10mm thick plywood sheet.

I have a MM-1000 spindle with a Stepcraft machine.

My settings are:
21000 RPM
40mm/sec feedrate
1.3 pass...

Hi,

I bought a clamping nut here

And I also bought from the same website, a 6.35mm collet here


I thought these would fit together, but they don't.
Is there any clue to what I did wrong in...

Thanks ger21!
I'll try that. Compensating by reducing depth seems like a viable solution.

I'll report back with good/bad results.

Hi,
I'm a bit confused from all the answers.
When I try to put my bit data into FSWizard for example, the result is to run the 8mm bit at 110 mm/sec, with 8700 RPM... MY machine can only go 50...

@ger21,

But lowering the RPM and raising the feedrate would make the bit cut less smoothly and go faster through the wood... isn't that the opposite of what I'm trying to achieve?

Hi,
Okay thanks. I think also compression bits would work better.

You say 'try running faster... 5mm at a time', but this is an 8mm diameter bit, and my pass depth was 3mm... so 5mm would be...

Ah, my mistake indeed..
Thank you for the clarification :)


Do you have any suggestions about the other issues I mentioned..?

I'm using a Stepcraft 840, with a MM-1000 spindle.

The bit is attached in an image here.

It doesn't make sense to me to run it at that feedrate... The machine max is 3000mm/min, so that's...

Hi,
I'm milling a profile cut full depth on a 10mm plywood piece.

I'm using an 8mm, 3-flute endmill, downcut.
My settings were:

16000 RPM
5mm/sec feedrate

Hi,
I've been trying to use the woodburning pen here.

I've done many tests trying to burn a QR code, but several things keep ruining the tests:

1. After about 30-40% of the job is done, the...

Hi,

Followup issue:

I tested another time with the 8mm bit, with the following settings:

8mm bit, 3 flutes
5.1mm pass depth
10.2mm cut depth
30% stepover

Can I use ER20 collets with the Kress nut?

What's important is that the nut fits the spindle, right?


What about this nut?

Hi,
Yes I obviously looked at that, but the parts from stepcraft have an outrageously high shipping cost to where I am... that's why I am looking for alternatives, either amazon or ebay.

What I'd...

Hi,
I've got a Stepcraft machine and a MM-1000 spindle.

I have the clamping nut that came with the spindle, which has a neck of 15mm and a hexagonal top part of 5mm, 20mm total.
You can see it...

Hi,
Thanks. I've searched the website FAQ and the general rules, but there is no 'help'... can you direct me to that information?

Hi,
There are 12 toolpaths, from 'profile' to '3d finishing' and all between.
I'm wondering about the difference for these types:

What's the difference between 'Pocket', 'Inlay'?

What's the...

Hi,
I used the FSwizard before setting it up, but I didn't get your results. Can you explain perhaps a bit what you put in the setup there? I put the diameter and sizes of the bit, and the material...

Hi,

I am working on my first 3D milling wood piece. The 3D model is a concave fruit bowl, with multiple concave parts to it.
I'm using a stepcraft 840 machine, with a MM-1000 spindle.

Hi,
I've got the Stepcraft CNC machine and I'm doing tests for their 'woodburning pen' attachment.

The attached .dxf file is a vector image of a tiger, with a lof of curves and points.

Follow up question:

If I want to mill a 50mm thick wood piece, with a 'roughing' pass, using an 8mm bit, are these settings okay? :

End mill : 8mm, 2-flute
Pass depth: 4 mm
Stepover: 1.6mm...

Hi,
Thanks Craig and ZASto for your help!

Since I didn't have another 1mm bit, I switched to a 2mm one, with the following settings:

End mill : 2mm, 2-flute
Pass depth: 1 mm
Stepover: 0.4mm...

Hi,
I'm using this setup:

Material: 3mm plywood with 6mm wasteboard.
End mill : 1mm, 2-flute
Pass depth: 0.3mm
Stepover: 0.1mm (10.0%)
Spindle Speed: 15000 r.p.m
Feedrate: 25.0 mm/sec...

Hi,
I've got a .dxf with 2500 circles in it. Their diameter ranges from 1.75mm to 4.4mm.

What is the best way to make simple holes according to those diameters?

- creating a drilling path will...

Thanks.
You mean to say that the capacitors and all the other electrical control is already inside the driver right? No resistors or capacitors required between the Arduino and the Driver / NEMA42 ?

@Jim Dawson

Thanks!

Is there a particular power supply I need for the driver?

I also want to control it with Arduino, do you know an example wiring scheme for that? I've done it with NEMA17...
