@tecno said in M950 output on 1XD:

Lets blame the bloody foreigner

Absolutely not. We're all foreigners to someone, which makes us all equal!

I think I've sussed it, @jay_s_uk.

I've got the M564 S1 H1 line in my config.g file, but whilst 'playing' with getting my axes working I've been using M564 S0 H0 to allow me to jog - not realising I should have used M564 H0 S1.

Thanks anyway

I've had quite a lot of help on here over the last few weeeks, most of it coming from users with 3D printers rather than CNC machines.

This made me wonder how many CNC users there are!

So here's a quick poll, which I'm happy for Admin to delete if I'm overstepping,....

This is probably more relevant to CNC users, but is there any likelihood for a future control board to support the (currently) separate function of a PWM to Voltage converter, like this?

Using one of these isn't overly complicated but it would be so nice to be able to just plug a milling motor, like the Sorotec, Mafell or AMB/Kress directly to the control board and configure it within config.g.

I've found with the separate card it's almost impossible to 'tune' it accurately to provide accurate speeds.

Or, maybe, an add-on board..?

Pretty please?

Click in the field...

Not sure if this is what you wanted, @fcwilt, but here you go:

The machine is a RatRig 1075 KillerBee, although I've made a few amendments to the supplied machine, including using 4x proximity sensors instead of limit switches, and redesigned the spoil board supports. It has a Duet 3 MB6HC control board (as you already know!) connected via a wired network to a Microsoft Surface Pro.

Most of my work is done on my iMac, which is in the house, so I connect to the Surface Pro and the Duet via a wired network using powerline adapters.

Apart from my own knowledge limits, everything seems to work well - but the proof will be when I eventually make something!

@adamfilip
Or read this thread and this thread...

Here's the updated connection diagram:

...and this is the code from the config.g file:

; Milling motor and relay configuration
M950 R0 C"vfd+out7" L4000:25000 Q1000	; enable router relay on out7
M563 P0 S"St George" R0 		; assign spindle 0 to tool 0 and name it St George
T0					; select tool 0
M5					; ensure motor is turned off

Note: I have used this relay to provide mains power to the milling motor, which is activated from Out7 in this case. I guess any Out could be used, but the code would need to be changed accordingly.

Many thanks to @dc42 and @jay_s_uk for helping me resolve this, and I hope this diagram will be of use to others.

Thank you to Support (and @Phaedrux) for helping me with this issue, which is now fully resolved.

Thank you, @dc42.

I was getting a bit tied up with this last night, but in the cold light of day - and after a good nights sleep! - a clear look at the problem certainly helps.

My thanks to @JoergS5 for pointing me towards the Z height, and everyone else who joined me on this journey.

Now all I have to do is find out why and prevent it from ruining my day again!

Thank you, @T3P3Tony

I was glad to help where I could, after all the help I had had!

@Phaedrux

Hmm, interesting thought. No, it wasn't something you said

@jay_s_uk
It's been a ride, for sure

I'm out of here, guys.

I decided to sell my Duet3-controlled CNC and bid it a final farewell today - to a very excited new CNCer.

I pointed him in the direction of this forum, so hopefully he will join your ranks very soon - if he hasn't already.

Before I go, I would like to thank all of you who helped me - directly or otherwise - and to wish you all the best for the future.

By the way, if anyone wants a spare Duet2 with an ethernet module, I happen to have one here in the UK, (courtesy of @jay_s_uk). Make me a reasonable offer, via PM, to include postage and I'll send it out once I've been paid and have the delivery address (UK preferred).

Good luck, guys and gals.

@achrn Whoops! Thanks for that

It's time for me to move on from my RatRig 1075 KillerBee CNC machine, which has served me well with my hobby over the last 12 months - and yes, it's only a year old! It is fully configured and ready to run - you only need to provide a PC.

I’m selling my RatRig KillerBee 1075 CNC milling machine, which is fully configured and ready to run. This would suit anyone with an interest in CNC woodworking hard or soft woods, and those who wish to produce machined woodworking for a new or existing business. The machine is a solid, properly fettled woodworking machine, also capable of machining non-ferrous metals, acrylic and other materials.

The CNC machine is controlled by a fully configured 32-bit, Duet3 control board via a 24v power supply, both of which sit inside a fan-ventilated enclosure. The enclosure can be mounted on the wall or beneath the worktop.

The CNC machine is constructed from 2040 C-beam aluminium extrusions and 8mm thick steel plates for exceptional rigidity, and the MGN15 leadscrews on all four axes, which are all fitted with needle roller thrust bearings, are driven by high torque NEMA23 1.8degree/step, 345oz/in stepper motors. Proximity sensors are installed on all axes, providing auto-alignment of the Y axes, and flexible drag chains provide cable support and management. The work envelope of the machine is 550 x 788 x 100mm.

The CNC machine was bought from new in March 2022 and comes configured and ready to run, but you will need to provide the laptop or PC to access the interface of the Duet3 control board via a web browser, via a network cable.

The milling motor is a Sorotec SFM 1000 PV-ER, which has soft start, infinitely variable speeds between 4,000 and 25,000rpm, idle speed reduction, constant speed under load and integrated overload protection. It has a ER16 collet with high-precision concentricity of <0.05mm at 25mm (in the cone < 0.01 mm) due to the balanced armature and. An enclosed double ball bearing is used for better absorption of axial forces. It comes complete with a 1/8" and a 1/4" collet and a 43mm mount and dust shoe.

Also included will be the spoilboard, which is practically unmarked. It is manufactured from 25mm thick, moisture resistant (green) MDF with 4, 19mm t-tracks and an array of threaded inserts to hold the workpiece. The spoilboard is removable to allow for milling the ends of boards for cutting dovetails, although a cut-out will be required through the table/surface it will be mounted on.

If you have any questions, please feel free to make contact, but it’s highly recommended you come to see the machine in action, to explain its operation in more detail and demonstrate it working.

It’s located in north Wiltshire, on the border with Gloucestershire, in the United Kingdom.

Payment by bank transfer only, please, and you can take it away once payment has cleared. Not before, sorry. It's too big/heavy to ship, so it's collection only.

Priced at £1250 including the Sorotec milling motor and mount or £975 without.

The Killerbee can be used with a Makita RT0700CX4 Compact Router or similar, and I can provide the 65mm mount, if required.

@YYCSparks

I think, but I'm not completely sure, if it's not the same thing. You just need to make sure the design file shows the correct starting point, i.e. the surface of the material or the baseboard, and the correct corner or centre of the stock.

I think...

I'm not going to be able to help you with this issue I'm afraid, as I had the same occur to me with my Shapeoko machine a couple of years ago, and Carbide3D were unable to resolve it as it was always my fault, apparently - and part of the reason I sent it back to the retailer.

Carbide Create, when used in conjunction with a BitSetter and a BitZero is flakey at best, dangerous at worst - even on Carbide3D's own machines - so I would be reluctant to run it on (what appears to be) a different manufacturer's machine. Are you using their control board (Carbide Motion) to run the machine or, as you're posting the question here, a Duet board?

What would help any potential support response is to provide the Carbide Create software version, exactly what control board (and firmware version), maybe a copy of the config.g file, and what machine you're using.

Also, have you checked the gcode file in a viewer, eg NC Viewer?

I'm not sure if I'm being a bit too simplistic here, but this is what I do, after producing the GCode toolpath for surfacing, usually with a 0.15mm depth of cut, or sometimes more...

Run the toolpath. Once complete, if there are still low spots, lower the spindle/motor to Z0, then lower it again to the toolpath's cut depth (0.15mm), reset Z0 and rerun the toolpath.

Continue as necessary, but as you get closer to 'flat', you could reduce the 0.15mm accordingly.

@wilriker
Sorry to have to keep asking silly questions, but i've tried to run RFM from the folder it's installed in, from the command line in Windows, and I get the error:

-domain is mandatory

I've used both the IP address and domain name of the control board, i.e.:

rfm backup -device Weeble //Libraries/CNC File O:/

and

rfm backup -device 192.168.1.121 //Libraries/CNC File O:/

With the same result.

Have I missed something (else!) please?

Thank you
