Re: [Emc-users] Control a hot wire foam cutter using LinuxCNC?
Hi Peter, I just figured out how to get it working again. The patch seems to be based on a snapshot of the master branch somewhere at the end of January. On my machine I can reproduce the (very nice) results with these commands: git checkout dcbaa105aaa5494ba5eea296ca66df893bd5c9b6 -b xyuv-sammel-28012012 git apply --verbose ../0010-foam-xyuv-Modification-2.6-pre.patch cd src ./autogen.sh ./configure --enable-simulator make -j 2 . ../scripts/rip-environment linuxcnc (then load the foam-xyuv.ngc) By the way, I'm also toying around with with model air planes. I have a small project at gitorious which can be used as CAM generator. https://www.gitorious.org/foambladesuite It can currently read a special kind of DXF files and export them to nc-code. LinuxCNC integration is still very beta, but we are going to improve soon. I'm going to do an extra announcement when I've tested it on a foam cutter...

Re: [Emc-users] Control a hot wire foam cutter using LinuxCNC?
Hi Michael, Thank for the hints. I will soon try it out and report about the success. I'm using a program called ProfiliPro from Stafano Duranti (http://www.profili2.com/eng/), which produces quite accurate g-code and is easy to handle. Unfortunatly it's not free, but the 60€ are worth for it. Of course it would be fine if a similiar program under a GNU or what ever free licence would come out. If you are interested in the configuration files, please let me know. It would be a pleasure for me to give them to you. I would also help with testing the outcome of your g-code on my foam cutter.

Hi I'll go to the workshop later an take a few pictures. I just realised we had a photo on our website.

Re: [Emc-users] Control a hot wire foam cutter using LinuxCNC?
2012/1/20 Florian Rist fr...@fs.tum.de: Hi Viesturs Do I understand correctly that actual layout of the joints in Your machine is that rotary table rotates around vertical axis, but portals are alligned so that XY and UV planes are vertical and Z is horizontal? I opened the link You posted in first message, but I saw some gantry routers there. Uh.. sorry for the confusion. If we assume a natural world coordinate system, with a horizontal xy-plane and a vertical z-axis, the machine consist of two parallel vertical portals (parallel to each other and the z-axis, orthogonal on the xy-plane) and a rotary table located between the two portals. The axis of rotation is parallel to the z-axis. The rotary table top level in z direction on on the lowest z level of the portals. Could You, please, draw and paste somewhere a sketch? I kind of understand, but am not sure. To be able to process different sized foam blocks the distance between the two portals can be adjusted rather easily, the rotary table stays in the centre (horizontally) between the to portals. So it'd be good to be able to adjust d value using axis. I don't know if this is possible. If not I'd have to provide a set of different configuration to chose from, which would be fine, too. Hmm, maybe I could use the X word to specify the d value? I created kinematics module, where I had an offset value, used for rotary joints to compensate displacement of nozzle tootip along X and Y, when rotary joints tilted the head. The thing is that the offset value was feeded in kinematics module like a HAL pin. And I think that it means - it could be adjusted on the fly as machine is running.

Re: [Emc-users] Control a hot wire foam cutter using LinuxCNC?
2012/1/19 Florian Rist fr...@fs.tum.de: Hi, has anyone ever used LinuxCNC to control a 5axis (two x/y-portals and a rotary table )hot wire cutter? I own one of these machines: http://en.step-four.at/hp2/index.php?action=450 And I'd like to overcome some of the limitations of the provided controller software. The hardware side is simple: Stepper motors controlled by two parallel ports. So that should be no problem, but the kinematics bother me and I'm unsure which axis I should use. X and Y for the first portal, U and W for the second and A for the rotary table? Or X and Y for the first portal and A and B to specify to angels of the wire and C for the rotary table? This would make it necessary to calculate the coordinates on the second portal in the kinematics module. Any suggestions? Since both of these options are possible, I think that the choice depends on: 1) Your skill and will to work on kinematics module; 2) ease of g-code generation for each of these options; Actually, if the wire slope is specified as 2 angles, then it should be pretty easy to set up kinematics, because offset between portals along Z is constant, right? So pos-u = pos-tran.x + offset*tan(B) And pos-v = pos-tran.y + offset*tan(A) Plus/minus signs should be checked, but I think that this basically should fit.

Hi Viesturs Since both of these options are possible, I think that the choice depends on: 1) Your skill and will to work on kinematics module; Hmm... I one compiled the millkins kinematics module (trivial kinematics extended by XY skew correction), and I'm more or less familiar whit C/C++. 2) ease of g-code generation for each of these options; For G-Code generation I plan to write a simple script that runs within Rhinoceros 3D and take a ruled surface (and the position of the rotary table) as an input to generate either the two polygons or one polygon and the angles. What would you think makes more sense as tool path specification, a x/y positions and three angels or two x/y positions and one angel? Or something completely different that I missed until now? Actually, if the wire slope is specified as 2 angles, then it should be pretty easy to set up kinematics, because offset between portals along Z is constant, right? So pos-u = pos-tran.x + offset*tan(B) And pos-v = pos-tran.y + offset*tan(A) Well, the offset Z should be constant, due to the poor build quality of the machine it is not. But for now we can assume it is constant and known - compensation of skew in the portals, planarity of the portals, misalignment and so on is something to work on later.
