General Mach Discussion / Re: Help Configuring Limit and Homing Switches

Hi, Mr.Chips

Your sw's are setup correct, you may need to set the "Active low's" from X to "Check" If seeing limit error all the time.

You may need to do the Same with the E-Stop also further down the window above, If it's flashing or not responding to the e-switch.

Also make sure the Emulated-es are X and not Checked.

There's a setting to change the Home Dir. It under Config, Home & Limits Page.

Yes Mach row's whether your homing or hitting  limit's and when it's working correct should move just off the switch.

In fact you can just use one pin and run all 6 sw's in seres if your not doing something special.

Let us now What else is going on.

Hope this Helps, Chip

Beaten to the post once again !!

Hi Tom

How big is the table and motor ?

There are a couple of stepper boards that have the Timer built in.

I need to dig around hear and find the info, Mostly for small steppers, NEMA 23 size motors.

Hears a basic diag.

Thanks, Chip

Hi, Chrispol

Try setting your Accel UP some, Between lines it's slowing to 9 every time.

If "F" speed is below your accel speed it takes priority.

I usually set the accel up to a point that steppers will slip or servos would trip, From a stopped condition (well maybe not that fast for some servos thy get pertty scary).

Then take the value and reduce it some for no slip/lost steps, 900 to 9 is pretty large.

Use G00 Moves to test these speeds, May need to back off your 900 max. value after testing.

Hope this Helps, Chip

Hi, Darc

Did you start with a .Lset screen set, If not you'll need to rename it from .set to .Lset.

I use a program called XnVIew to rename them.

Hope this Helps, Chip

Hi, All

Download MachR2.55, newer LC in there LC2.55 or Download LazyCam 2.49 it's really 2.55 now.

There are still issues with arc's, rapids dashed lines though it seems better.

When offsetting and pocketing, Zoom in to the drawing on one of the red lines, There's  an issue with the sensitivity in the prosessing rutine.

Art has them listed for some tweekiing

Hope this Helps, Chip.

Hi, Tom

One way is to use a DPDT ON ON switch, Run your rot. table step & die  wires to the center terminals, Mach3 A axis S/D to one side of the switch and a LM555 oscillator to the other side.

This would allow you to set a cont. speed for your spindle/rot. use and switch back to A axis use.

PM your phone # if in USA / CA, I'll give you a call after 9:00 Eastern tonight.

Thanks, Chip

Have you checked all the power supply voltages ?

If you hold the reset button in (if it has one) do the drives Lockup ?

Can you identify the voltage led that's coming on ?

If your encoders have power on them, Check with a volt meter at the +_ 10 volt terminals for voltage, Between CPU and Servo control.

Then turn the servo motor by hand and look for a voltage change, One way - volts the other way + volts ?

Hi, Tony

If your ball screws have slop, Liner slides will cause your servo to hunt and seek like mad.

Trying to come up with an interface to combine liner slides and motor encoder would be expensive.

I have interfased liner slides on one mill, It had pretty tight ball screws and is somwwhat more nervious compared to motor encoder mills.

Spend your money re-building your ball screws or buy new ones.

Not saying it can't be done.

Just My Opinion, Chip
