JasonB, i thought I was looking at my machine for a second. I do sharpen flat ones on a universal grinder. Not sure I can sharpen ball endmills with any accuracy that's worth the pain though. But I'm going to continue using the HSS one until it's dull. I've received some carbide ball endmills from Arc. But it distorted along the length after cutting on my bandsaw, anyway. I'm using whatever scrap metal I found in my cupboard to mill from.
#Filemail going really slow how to
I can't work out how to clamp the whole length without collision, so I'm using a vise with a chunk sticking out. About 25mm at a time and then cutting the machined piece off and starting again. I'm only machining a part of the extrusion. I have a load of 12mm HSS ones I bought a while back and just went with those for this job.
I'm not sure why I am using larger diameter cutters for this job. It just sounds loud in the garage with the noise reflecting off bare walls. But I've no idea how well the low frequency vibrations transmit through walls. Outside my garage I can hear surprisingly little. Where did you get those lovely wavy parallels from? I definitely need those! I unselected the top face and it seems to be doing something similar to yours. Great job! Now, how did you get scallop to do one side at a time? Mine's doing a column at a time and then going to the other side, back and forth. I really appreciate the help to sort out my machine and all the advice. But the carbides were cutting as if they were tackling aluminium or even hardwood. I've always been nervous about loading the cutters too much. That's one amazing project you've got going there with that engine. I don't have a 25mm long carbide endmill at this moment. Machining vertically would have been much simpler. If there's a vice that doesn't lift, please suggest one. I managed to minimise it by hammering the stock down, as recommended in other threads. But did have trouble with my Warco vice lifting when holding stock on the last couple of millimetres of the jaws. Thread: Sieg KX3 Y_Axis Skipped Stepper Steps😢ĭidn't have time to look at the replies as I was machining the pieces. Cutting a slot in steel is a completely different ball game, obviously. My feeds and speeds were massively optimistic. I tested some contouring with F360 a few days ago with no mist or coolant and got my 6mm carbide bit to glow wonderfully. JasonB, I can see your contouring above is quite slow too. I had to go really slow with multiple depths and used lots of coolant. I made these a few weeks ago with Aspire, before I got started with F360 CAM. I'll try your suggestions, as I need to make 3 more. I was using a 1mm stepdown with a 4 flute endmill. I just realised I used F360 for the flanges. I don't think it's ramping into those tabs, for some reason. I've tried tabs, but got some nasty vibrations with my non-centre cutting endmills. Thread: Further Adventures with the Sieg KX3 & KX1 Also, doesn't that affect g-code too?!Īnyone have any ideas what's going on with jogging very small steps? How do I prevent the DRO from changing when no steps are being output to the stepper motors? When moving the wheel slowly, I note that I can change the DRO and not get any stepper motor motion. Moving in those increments is not practical, anyway, right?īut my iMach P4-S pendant does use 0.001mm (actually it's 0.002mm) steps in velocity mode, when moving the wheel slowly or at the beginning (or end) of an acceleration when getting up to speed in velocity mode. That's using the arrow buttons on my keyboard. Ok, so jogging in 0.001mm steps doesn't appear to move my Y axis, despite the DRO incrementing and decrementing by that amount. Why not? Yes, it's a Y axis problem again. It's not keeping track of Y in machine space. The Y stepper doesn't do anything, despite the DRO changing. The X and Z axes steppers also appear to move the carriage or column by 0.002mm on alternate clicks, but haven't measured but can hear.
The X-, Y- and Z- buttons change the DRO by 0.002mm, on alternate mouse clicks. I can't get any DRO axis to change positively or steppers to move.
#Filemail going really slow driver
JasonB, could there be something in my Mach3 XML file that is causing Y to behave differently? Or could it be a stepper driver issue?Ĭopying JasonB and using the mouse to jog any axis, all axes change the Mach3 DRO by -0.002mm, as long as it's negative.
