Re: [Emc-users] A lot of input/output. Cheap
Hi, the big advantage of the mesa-boards is that they are well suited to drive relays and other kinds of devices. An Arduino or similar board only has TTL or CMOS IOs which need to get adapted to your actual IO voltages/currents. Parallel Ports also need some additional protection/drivers to handle 'realworld' IO. Depending on the actual project it might be possibe to design you own IO-Board with appropriate IO circuits. signature.asc Description: OpenPGP digital signature -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] SCARA Kinematics WTF!?
Hi, First of all, thanks for your reply andy. I know of the ja-branch, but unfortunately it isnt in master. But I am willing to help. JA also needs documentation, I only found a few wiki-pages. In the meantime I did some more tinkering and made some progress. In HAL the joints0-3 now map to axis.0 ... axis.3. In the .ini-File I have axes 0-5 defined, with 4&5 only being there so they can be homed. However, it seems like the speed/acc settings for C-Axis in world mode are read from the AXIS_5 section. So I added sane values there. Without the speeds default to '1', which is horribly slow. I will provide a patch for the sample-config which will document this behaviour. For now, two problems remain: 1. Z gets inverted when switched to world-mode. This is due to lines 94 and 162 in scarakins.c. However I dont understand why this is desirable? This odd behaviour can also be reproduced with the SIM-config. Most likely I will change the sign recompile scarakins. Or is there an simpler way? 2. Illegal moves are not detected. This is the work area: http://i.imgur.com/CGLhgwY.png When moving from "X0 Y-450" to "X0 Y450" the machine runs into the hardware limit switches. Is there any way to make the TP (or any other comp) detect those moves prior to the execution? Similar to the softlimits on trivialkins?

[Emc-users] SCARA Kinematics WTF!?
Hi, Sorry for the long confusing post in advance. I am having some troubles with scarakins: For reference, a copy of my current config: https://ca.rstenpresser.de/~cpresser/20150907_linuxcnc-config-hirata-scara.tgz First of all, I dont know which Axes/Joints I need to define in both the .ini and .hal files. The real machine has 4 Joints: http://i.imgur.com/bhsfqXk.jpg - Joint0: Inner Arm - Joint1: Outer Arm - Joint2: Linear Z-Axis - Joint3: Rotary C-Axis (rotates around the Z-Direction) In the example-config-ini-file the following AXIS are used: (/usr/share/doc/linuxcnc/examples/sample-configs/sim/axis/vismach/scara) - [AXIS_0] - [AXIS_1] - [AXIS_2] - [AXIS_5] The corresponding HAL-File however uses net J0pos <= axis.0.motor-pos-cmd net J1pos <= axis.1.motor-pos-cmd net J2pos <= axis.2.motor-pos-cmd net J3pos <= axis.3.motor-pos-cmd This does indeed match the 'scarakins.c' source file. A comment in line 73 says: /* joint[0], joint[1] and joint[3] are in degrees and joint[2] is in length units */ With the example-config the C-Axis is slow as hell. I tinkered around a litte and found that when I use axis.5.xxx for the C-Axis the speeds are okay. It looks like is isn't a good idea to use ini-entry [AXIS_5] with the axis.3.xxx-pins. But now I have axis.3.xx and axis4.xx unused. This makes linuxcnc unhappy, when trying to switch into world-mode it complains that those two axis aren't homed. So I added homing to those two axis, thats where I am now. Now switching into world mode actually works. But with errors, the GL-Preview isnt happy: http://nopaste.linux-dev.org/?755109 (I fixed that by uncommenting those lines) Now comes the FUN part. When I rotate the C-Axis by hand (servo amps disabled) the B-Axis-Value on the DRO changes. Video: https://ca.rstenpresser.de/~cpresser/MVI_2799.MOV Any Hints (besides not using scarakins!?)

my Debian Wheezy machine, I keep getting the authorization pop-up to

Or does this actually mean my wireless signal from the router could be

A sticker with a size of about 190x130cm would be around 4-5Euros. If features digital printing with 600DPI on self-adhesive foil, including a countour cut around the pengiun (not like the first one I created). I reside in Germany, but worldwide shipping is not that expensive since it can be send as a regular letter.
