Same is true for any post made by anyone on the forum. 100% voluntary. No one is paid to participate. The forum is hosted and maintained by Newfangled to give the DIYers a place to work together.

There really shouldn't be any political workings in a forum. The only thing I have seen over the years is truths yielding to political correctness. This usually helps no one and at best is like going around your elbow to get to your thumb. Myself, I'm a call it like it is kind of guy and I think most of the people that post the most accurate information are as well. I can't tell you how many post I have seen where someone ask a question and in short order have the exact fix by someone yet the post go on forever because the person looking for the answer did not like the answer. I don't waste my time on such nonsense anymore. Life is too short for that. I think all of the most knowledgeable here feel the same way. I know lots of others did but you won't see them posting at all........... they gave up.

This will create a new file and pop up a message box where you enter the desired feed rate.

Just add the function to screen load script and call the function from a button.

Code: [Select]

function CreateNewTeach()

local MyNum = wx.wxGetNumberFromUser("Select or enter a feed rate", "Feed Rate:", "Teach Feed Rate", 50, 1, 1500) --Default, min, max
local MyGcode = string.format("(File created using CreateNewTeach function)\nF%0.4f", MyNum)
local Teach = wx.wxGetCwd() .. "\\GcodeFiles\\Teach.tap" --Define the file name and location
file = io.open(Teach, "w+") --Open the file in update mode, all previous data is erased
--file = io.open(Teach, "a+") --Append update mode, previous data is preserved, writing is only allowed at the end of file.
file:write (MyGcode) --Write the Gcode file
file:flush (Teach) --Save written data
file:close (Teach) --Close file
end

One thought I had is "How close is the drive that is picking up noise to the other drives? Are the step and direction durations set the same for all the motors in motor tuning".........

This triggers lots of thoughts in my mind but none that have not been covered by previous replies or links in those replies. You're just gonna have to dig into it (following the previous replies) and experiment until you can remove and repeat the problem at will. When you can do that you can be pretty confident you know what to do to eliminate at least one of the problems (you may have several).

Separate wires (put some distance between them), change ends the shields are grounded on, float or bond commons, etc.

The best tools to use to fight noise issues are detailed wiring schematics and component layout drawings. Those 2 are the first steps in mitigating noise issues. Assuming they match the machine exactly you can use them to check for ground loops, star ground, proximity of components, etc. Without those the best anyone can do is make educated guesses. That route usually ends being way too much wasted effort and time to guess down problems that should have never existed in the first place. Not a game most will take time to play.

Glad you got it sorted. Mitigating EMI is a lot like black magic. There are common practices (which is a good place to start) then there is the thing that actually fixes it. Which may require some nose twitching, a crows foot and other ingredients. Consider yourself lucky if your first attempt fixed it.

All good info fellas.

Tweakie has a very good write up on noise somewhere. I think it was on his website.

This is to a post in members docs..... http://www.machsupport.com/forum/index.php/topic,25616.msg180583.html#msg180583

Depends on how your doing the jog. The on screen buttons use them. Jogging through script doesn't have to.

Not sure what all you are doing but keep in mind, jogging with on screen buttons, jogging for script and jogging from say a pendent are 3 separate things. Changing a setting in one will not set it in the other unless you handle the switch in the script............. or they all run the same functions.

Maybe not the answer to your question but this should work in place of your script below.

for i = 0, 5, 1 do
   mc.mcJogSetInc(mInst, i, SetInc) -- set inc for axis
end
