Softlimits are normally referenced from your home switches.
Do you just want to use softlimits instead of physical limit switches?
Hi.
My name is Ed and I'm new to CNC machining. I own a Sherline 5400 mill (and a long bed Sherline lathe) and have just converted them both to CNC. I have a DeepGrove1, 4 axis controller box with Gecko 540's and 270oz nema 23 motors. I'm running Mach 3 and Mill Wizard. I also have a Soigeneris SSENC-1 Ethernet SmoothStepper System as well.
My question is this. Being new to CNC (translation: I know very little), I've heard that on these smaller mils/Lathes, that you don't need to put Homing Switches on then, but you can use Soft limits to setup your machine coordinates. Is that so? I have my mill's motors on, have gone through doing my "Motor Tuning, and now I'm ready to setup soft limits. Could someone familiar with a Sherline setup like mine, provide me with a little help completing mine? I've read the Mach 3 pdf, and watched a bunch of video's about it, but they don't relate to my setup. I'd really appreciate it.
According to the Sherline Mill's site, my mill's travel spec's are as follow': • X axis Travel: 8.68" • Y axis Travel; 5.00" • Z axis Travel: 6.25
Thank you.

Hi Ger21.
Thanks so much for responding to my need for help. Basically yes, I'm trying to run my Sherline mill without Homing switches but would like to avoid crashing my machine all the time. Is this possible and if so, how would I se it up. Thanks so much.

You need to jog the machine to a repeatable position, and click the Ref All button, to zero the machine coordinates.
You then set your softlimits relative to the machine coordinates.

Hi Ger21.
Thanks for the advice, but I'm very new to the whole CNC thing. I'm not quite sure how to "jog the machine to a repeatable position". I understand the jog part, but unclear about the "repeatable position" aspect. Any chance you could help me understand it a little better? I'd appreciate any help you could offer. I'm dying to run my first piece of G Code on my setup. Thanks so much.
