Engraving: short and fast strokes vs long and slow strokes

Hi guys. When I choose to engrave several copies of the same piece, (i.e. acrylic key chains) I can choose to engrave each group individually or, engrave all at once.

The first choice results in short rapid movements along the X axis, back and forth. This is what I usually choose to complete the job faster.

However, I am worried this fast reciprocating movement might wear my hardware faster (motors, pulleys, guides and belt) than having the head run all the way along the X-axis rail and then return, even if the work takes longer to complete.

Any input is greatly appreciated.
Thanks.

Run it faster and increase wear or run it slower for a longer period, which is worse?

I have a 40W, China Blue… mine will run at 1650mm/s and it’s fun to mess with but not of much use for anything else…

What you gain is the acceleration, which reduces job time as the machine can slow, stop, change direction and speed back up…

I tuned a little cnc3018 up to be quite fast for them… however it walked all over the table and shook most of the screws out of it… I ended up back in the area for which it was configured…

IMHO, if it doesn’t shake the machine around, you’re probably ok…

It probably has speed limits within the Ruida so you can’t really hurt it… assuming it’s configured correctly…

I’ve had mine a while and haven’t seen any issues and mine can run pretty fast…

Are you changing the machine settings or just optimising?

:smile_cat:

My machine is a Chinese 80Watts, which is quite heavy and still shakes when the head moves back and forth in really small engravings.

I have not messed with the machine settings, so I don’t think I am putting it under too much stress.
