i have been using my new 1100 for few weeks without any issue. But today when I ran a new project it started just fine until the first tool cycle was complete. My code calls for M998 go to tool change position but the z axis stayed at the last cutting position and I herd some odd motor sound for few seconds and every thing stopped. Mach3 asked for the 2nd but I could not place the 2nd tool since I had no z hight. I manually raised the z axis few inches so I could place the 2nd tool. when pressed start cycle, the z axis moved rapidly and crashed into my workpiece. I checked the code line by line and did not see anything unusual. Am I missing anything or doing something wrong?
