[Emc-users] Gecko 203v
I had a noise problem with the 203v. I solved the problem by re tapping the 4-40 ground screw in the center of the Gecko's black heat sink. The heat sink is anodized making it non electrically conductive. My 4 Gecko's are all mounted on one common heat sink, and after making everything grounded the same, the noise was gone. I have US digital encoders on every motor, and Jon Elson suggested that I put a capacitor on the plus and minus power input to the encoder chip. The capacitor cleaned up the encoder signal's. US digital has a new chip that is more noise immune than the chip I used. I am using Ubuntu 10.04 LTS on my Emco FB2 mill, and LinuxCNC V2.5. The computer is an Intel Atom D945GCLF 2D. My system has been running for 10 years now just fine. I hope this helps. ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
[Emc-users] Easy to heat treat high speed tool steel
Have a look at Uddeholm Vanadis 4 Extra SuperClean. Uddeholm has more types of tool steel to choose from. This is from Uddeholm PDF. Pre-heating temperature: First pre-heating at600–650°C (1110–1200°F) and second at 850–900°C (1560–1650°F)Austenitizing temperature: 940–1180°C (1725–2160°F), normally 1020°C (1870°F).• For large sections, i.e. >70 mm (2.75") use 1060°C (1940°F).• For the very best wear resistance use 1100–1180°C (2010–2160°F).Soaking time: 30 min. for hardening tempera-tures up to 1100°C (2010°F), 15 min. fortemperatures higher than 1100°C (2010°F).Note: Soaking time = time at hardening tem-perature after the tool is fully heated through.A holding time of less than recommended timewill result in loss of hardness.Protect the tool against decarburization andoxidation during hardening.Further information can be found in theUddeholm brochure “Heat treatment of toolsteels. ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
[Emc-users] Fourth Axis
Hi Kirk I was looking for a answer to this question about 3 years ago and I did not get any help on this topic. I hope you will get some were with this problem. I am using "axis" for my screen in LinuxCNC, on my machine, and it displays the fourth axis in the same way as (Gremlin). I think the best way to fix this problem is to have two machine origins. The first origin would be your home position with the cube work space of the machine. The second origin that you could turn on and off as needed, would be centred on the centre line of the rotary table. By shifting the second origin from the primary machine origin the fixed work space would give you no G code out of bounds error, that you would get if the center line of the fourth axis was moved to the home origin. I think this would be a good solution to the problem of the distorted fourth axis presentation. If we could just get someone with the know how to look at this problem, every one with a fourth axis would appreciate it. A accurate screen presentation would be very helpful when checking a workpiece setup. Thank you David Pape -- Dive into the World of Parallel Programming.

[Emc-users] Displaying the forth axis with LinuxCNC 2.5.2
Hi all I have found that Rot4thaxiskins - "configuration of a 3 axis machine with an additional rotatory axis" has been added to LinuxCNC 2.5.2 ,is this correct? If Rot4thaxiskins has been added has anyone tried to use it? Have a look at my brothers web page, http://members.shaw.ca/rpape/ There is some of my projects on his web page to.

[Emc-users] How to get the A axis to display properly
I would like to get the A axis to lock on to my rotary table center line. I have upgraded to LinuxCNC/Axis 2.5.0 and the A axis is still locked on to the X axis machine position, G53. The INI line I am using is GEOMETRY = AXYZ. When I set the part position to be on the center line of the rotary table using G54 I thought that the A axis center would also move to the G54 position. The A axis is locking on to the new X axis position, example move, X axis plus 2 inches from the machine position then G54 G92 X0, then A will rotate at around the new X G54 position. But I can not get the A axis to lock on to the new Y,Z G54 position. LinuxCNC/Axis can work properly as you can see form the youtube video http://www.youtube.com/watch?v=R1DCXe9t3UE . The only information I can find is in the integrator manual V2.5, 2012-04-01 page 14/234. Please help me out! Thank you David Pape -- Everyone hates slow websites. So do we.
