[Emc-users] Rotary homing.
Hi all; I have just received a Sherline rotary table that I intend to connect to my KX1. I have added the wires, but have not physically connected the unit yet. Ok - I'm trying to add it in. I see the rotary axis in the view screen; and the machine seems to home correctly, except when I try and touch off the X, Y or Z axis; I get the "Can't issue MDI command when not homed" error message. Here is my hand-edited ini file - any silly/obvious mistakes here? I'm a relative newbie with this stuff, and thought I had it figured out. Thanks for any pointers. John A.

Re: [Emc-users] Joypad pendant, hal_input errors
Hi Sebastian; Thanks for the reply, and the ideas. I'm new to EMC, so there is a lot to figure out still. > What device is this, exactly? lsinput: /dev/input/event3 bustype : BUS_USB vendor : 0x54c product : 0x268 version : 273 name: "GASIA CORP.

Yes, the halmeter did work for at least one button input - I'm still figuring out how best to run these programs so I know what to look for. I have modified the "hal_input" program to just not print out the error message; but, if I have this issue, I wonder how many others might, too? I'll report back on progress; maybe it will help others. Also, any debugging you (or anyone else) wants me to do, just ask.

[Emc-users] Joypad pendant, hal_input errors
Hi all; After reading some of the messages on this list, I went out and purchased a wired joypad; it is giving me the following messages when I run: halcmd loadusr hal_input -KRAL GASIA Unexpected event EV_ABS ABS_48 Unexpected event EV_ABS ABS_49 Unexpected event EV_ABS ABS_50 Unexpected event EV_ABS ABS_51 Unexpected event EV_ABS ABS_52 Unexpected event EV_ABS ABS_53 Unexpected event EV_ABS ABS_54 Unexpected event EV_ABS ABS_55 Unexpected event EV_ABS ABS_56 Unexpected event EV_ABS ABS_57 Unexpected event EV_ABS ABS_58 Any idea what's happening here? I got a wired joypad because I'm always finding batteries dead when I come to use things - maybe I shoulda got the bluetooth one!

[Emc-users] Running! was Re: Beginner questions regarding axis.
Hi everyone; Thank you all for the help and guidance. Each email recieved was interesting and to the point, and I learnt something from each one. FWIW; here's the issues I had: 1) The microstepping setup; default to 2 in stepconf; G540 does 10; I thought of microstepping as "fractions", but it turns out that, of course, they are not. 2) Home location, Home Switch Location, now figured out; 3) Axis direction, positive, negative; although easy, I had spent time googling for axis direction before and came up blank; 4) Velocity and Acceleration values. It is all pretty obvious in hindsight, but that's hindsight, right? I do a lot with lower layers of OpenGL (including writing programs that run on GPUs) and X,Y, and Z have a bit of a different slant on things; so of course I had some pre-conceived notions there, even though I knew they would be different. I'm sure there'll be more tweaking, and of course G code programming to ensure that I really have it down pat, but it all looks good to go from here.

Re: [Emc-users] Beginner questions regarding axis.
Brian, Kirk, James; This is all making sense now - lots of good action happening downstairs. :-) > Also check your G540 for the micro step setting to be sure it matches the > values in your INI file that Kirk was referring to. Ok - just checking the microstep settings - the Gecko gives 10; the stepconf defaulted to 2; that'll probably be the last thing. I did manage to manipulate the ini file (thanks for the pointers and math) to give me the right movement, but would like stepconf to do this for me. I think tomorrow morning I'll be up and running.

Re: [Emc-users] Beginner questions regarding axis.
James; > Welcome to EMC2! I can't answer all of your questions... Thanks very much for the explanation; it looks like I had some of the axes going in the wrong way. I'm still trying to figure out how I get 1/5 of the movement expected; ask for 5mm X movement, and I get (via dial indicator) exactly 1mm movement. Still some stepconf stuff to work out. Like everything, it'll be obvious in hindsight ;-) PS - I'm using the Intel M525DW motherboard, and with hyperthreading turned off, seems to work absolutely fine.

[Emc-users] Beginner questions regarding axis.
May I ask a beginner question or two? I have a KX1, but with a G540. It is all "kind of" working, but maybe I have a conceptual misunderstanding or two. Can someone help please? It has been all connected together now for a day or so. 0) Metric machine, so all of the following is metric. 1) X and Y axis. limit/home switches working, but x and y axis is set to: Home Location -3.0 Table Travel 0.0 to 250.0 (110mm for Y) Home Switch Location 0.0 Home Search Velocity 1.0 Home Latch direction SAME Homed, table is to right, and close to vertical column. Q: Would it be better to have Home Location 0.0 and table travel -5 to 245? 2) Z axis - is "zero" top of travel? Home Location -10.0 Table travel -200.0 to 0.0 Home Switch Location 0.0 Home search velocity 1.0 Q: Is it right to have these negative values here? 3) I'm thinking that travel when homing in EMC2 is not correct, distance wise. I'm thinking that it is not moving as much as the readout on the screens say; I have 4mm pitch leadscrews, 1.8 degree steppers, directly coupled: Motor steps 200.0 Driver Microstepping 2.0 Pulley teeth 1.0 to 1.0 Leadscrew 4.0 mm/rev Maximum Vel 8.3 mm/s (machine says "Rapid moving, 1000mm/min; feeding speed max 500mm/min) Maximum accel 50.0 mm/s2 Looking forward to learning to use this machine in earnest, and thanks in advance for anyone who can pull the cotton wool out of my brain for me. ;-) JohnS Ottawa, Canada. -- BlackBerry® DevCon Americas, Oct. 18-20, San Francisco, CA http://p.sf.net/sfu/rim-devcon-copy2 ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
