I have only 2 choices in system/screen resolution vga and svga, so max is 800x600 and ref. rate 56 or 60Hz. I don't find the software to use to configure X-windows. Formerly I used older ver. of EMC2 Ubuntu and it worked fine my panel best resolution is 1024x768. Please somebody help me. Arto - Check out the new SourceForge.net Marketplace.

[Emc-users] Gear Cutting
Has anyone tried cutting gears with something similar to this arrangement? http://www.wallacecompany.com/machine_shop/Gear_Cutter-1b.png I was thinking a slot saw (gray disk) could be used, centered on the gear shaft(violet). The gear tooth form could be followed with Y while rotating the gear (bronze color) and incrementing X on each gear rotation until the width of the gear is complete. Or successive passes in X and incrementing Y and A could make a complete tooth so that one gear rotation would complete the gear. Slot saws aren't very stiff and don't side cut, so some other cutter would be needed. Part of my thinking is that I would like to avoid special cutters like those needed for normal gear cutting. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC/EMC CNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending Craftsman AA 109 restoration Shizuoka ST-N/EMC CNC) - Check out the new SourceForge.net Marketplace.

Re: [Emc-users] Installing a second parallel port
for the port, if it is a PCI or newer card, it will probably just work. Some old ISA and earlier cards had to be jumppered, but instructions came with them. Now 'just work' is another issue. The board can work, but you still have some HAL configuration to do to let EMC know how to deal.

Re: [Emc-users] Installing a second parallel port
Aaron, I bought my 2 parallel port pci card from Newegg. It is uses a netmos nm9815cv chip. After physically plugging it into the computer, I ran lspci -v from a terminal window to locate the port addresses. Thus far it was just plug and play. The next step is to edit the .hal file. You need add the port address to the hal_parport config statement and to add read and write functions to the appropriate thread (since I am running steppers it was the base-thread). Then you need to add the pin and signal connections to do what ever provoked the need for a second port. Alan --- Alan Condit 1085 Tierra Ct.

[Emc-users] Gear Cutting
Hi Kirk, Has anyone tried cutting gears with something similar to this arrangement? I tried to get my head round this method of gear cutting a while ago and gave up several times with a severe headache. It must be possible but it would have to be done in a number of increments unless the gear was very thin. I need to be able to cut gears with a cycloidal form and so most gears would have parallel flanks to the teeth with ogival tips. So, I was looking at centring the cutter in Z, moving it up to the right position to cut the flank of one tooth and ploughing it in to the tooth depth in Y. Then remove it to the start position of the ogive and then have a line of code rotating A clockwise and Z down simultaneously to end at the tooth tip position. This should give an ogival curve I think. The blank would then have to go back to the position just before the cutter is first fed in in Z, Y and A, index one tooth on and repeat the whole thing. When that is all done for the whole wheel, it would be necessary to start cutting the other flank of each tooth in the same way but rotating the A-axis anticlockwise. Having done that, X would need incrementing and the whole thing repeating again and again until the whole gear thickness was cut. For my purposes - tiny watch wheels, I could easily cut the wheel in one pass using a thin slitting saw and cutting on the sides of the teeth as I would only be cutting brass and, in any case, there should only be a very small area of contact. However, I got totally flummoxed trying to work out multi-nested routines and gave up until a dark winters night!! :-( What would be even more useful to me would be the ability to cut steel pinions this way as making them now is the bane of my life ( I'm just trying to sort out how to cut one with 5 leaves and an overall diameter of just 1.3mm ) ... I can work out the geometry OK but I don't seem to be able to convert it into working G-code... An alternative method of cutting might be to cut each tooth by cutting along the X axis and then incrementing the work in Y and Z and repeating like this in tiny sections until the whole thing is cut. The disadvantage here though is that the teeth will not have a smooth profile which could lead to unwanted friction. -- Best wishes, Ian Ian W.
