Hi, I have just ordered an AJAX AJAT210, CNC lathe that comes with Siemens 808D control. Does anyone have a suitable post processor for Edgecam, my favourite CAM software? I have been using Edgecam...

Hi Graeme,

What thickness and density is the Rohacell you are trying to cut?

I managed to cut through 30mm of 31 grade Rohacell with the edges remaining pretty square. I did this by reducing...

Hi Samay,

I'm not sure how the auto focus works and no, I did not get it on my machine. It really is not a problem re-focussing for different thicknesses of material. It is simply a turn of a...

Hi ksamay,

A honeycomb bed is very useful if you intend cutting very small parts. Without it, the parts would fall through the support rails. They don't come cheap and I think mine was an extra...

Hi Manish,

Over the other side, in West Lancashire, just outside the market town of Ormskirk.

One of the great things about using the laser for cutting Rohacell is there is very little waste...

I replied privately to Manish saying that Rohacell cuts beautifully with a laser. I have cut up to 25mm thick Rohacell and at that thickness it is best done in two or three passes on reduced power...

Hi Gerry,

Will the DROs be updated with information from the 'Toolchange' tab? I am presuming there will only be one plate thickness that is common to both the toolchange tab and the wizard. Same...

Hi,

I've just been running the screen, doing a couple of fairly large patterns. They required four tool changes, scaling to -1 in Y and a negative material offset for taking an extra 0.2mm off for...

OK, changes made to tooling and new file attached.

Was that a 10mm end mill or ball nose?

Mike

Heli Bee,

Just thought, my post processing does not include a spindle start or stop so don't expect Mach to operate your spindle with my code. I don't have spindle control, yet!

Mike

Hi Heli Bee,

I have just imported your stl file into EdgeCam and produced the attached gcode. I have used the same feeds as you have and used a 20mm diameter end mill for the roughing cut and a...

Referencing is available from the main screen, on the menu bar at the top of the screen. There are icons for Ref All, X, Y, Z and A if you use the four axis screen set.

Hi, One of the big things that Gerry has managed to solve with the semi-auto toolchange is that Z datums aren't always made on the top surface of a workpiece. Quite often the Z datum is the bottom of...

Hi Arbo,

Yes, that's exactly what happens. You only need to scale to -1 in either the X or the Y not both. Although it is possible to flip in both, you get the same image as the original and...

Hi, I think I was probably the one who asked Gerry to put the scale DROs into the screen set. They are absolutely brilliant for doing mirror images of things. Quite often I need to make two halves of...

Hi Tdiaz,

I don't understand - my laser cooling water has been in my tank for over twelve months now and I only checked it yesterday and it is still crystal clear, as is my spindle coolant water...

I have a forty litre tank, for the laser, and use a whole litre of antifreeze. My spindle coolant tank is only five litres and I use about one quarter litre in that.

Hope this helps,

Mike

Hi Hannu,

I use engine anti freeze in my coolant for both my laser and water cooled spindle. It works like a charm and twelve months later, the water is still crystal clear, albeit with a hint of...

Hemsworthlad,

You mean you didn't read through the whole thread to see all the details? :) Software is EdgeCam - as part of the British Space Modelling Team, I was able to get sponsorship for the...

Hi again,

I have just re-read post #12 and that is one monster of a machine at 15 foot x 15 foot :eek: I think that at this kind of size, MDF and plywood are out of the question for any of your...

Hi Chrjensen,

I have built a machine using linear rails with a gantry made from MDF and I regularly machine aluminium very successfully. My build log is here but be aware, it is very long :)

Hi Karthik,

My JCUT 4060 is extremely well made and robust and I would recommend it highly. However, having bought it direct from China, I don't yet know what the after sales service is going to...

Hi Neoman1,

I have to say that I am very pleased with the JCUT 4060. The build quality is very good indeed. One inevitable problem with lasers is the setting up of the beam. You have to be quite...

Hi Jeffrey,

Nice build - ahh, the ubiquitous road runner strikes again :)

Just a point - I assume you will be stripping the whole machine down shortly to seal the MDF? This really is a must,...

Hi Gerry,

OK, point taken - attached are some photos of a few of the moulds I have already made on my machine. I can't remember whether I have already explained that I bought a Syil SX3 for...

Hi everyone,

I must apologise for not looking in for so long but there are just too many interesting forums, most of which have something to do with machining and/or software, and trying to keep...

Hi MonoNeuron,

Thanks for the info and tip. I was never particularly keen on using the small, cheap, crocodile clip as in the photo. Strangely, the anode end had a small connector, similar to the...

Hi Dave,

If you look at post 20, you will see the rotary attachment that I have. Unfortunately, it comprises a chuck and a large, live centre in the tailstock. I say unfortunately because I think...

Hi Dave,

Yes, I am having fun - not sure the beam is set up absolutely right just yet, but I have been doing quite a bit of cutting. At the moment, I am cutting 2mm Rohacell foam (acrylic foam)...
