I would like to verify that we can only change the ram speed while it is running up and down. I have not tried to change the ram speed so far – it is still at the lowest “ 1 “ speed. There is a sign which says “ CAUTION. DON’T CHANGE SPEED WHILE STOP “
When we use the JOG button to move the ram,it is very noisy.Is that normal?
When we shut the ram movement, it stops at the very top ram position. That is good. If we want to stop at the very bottom ram position, is there any other way except the JOG mode ?
Ans for Q1:
Regarding how to change the Ram speed , EASTAR CNC-300A1 totally have 8 speeds, High /Low speed control by operation screen , It’s for switching 4P/8P (HI/LOW) two speeds main motor ,Besides 4 steps by Gear reducer speed change at left aide change lever , The Gear Reduce Inside with 4 slots to shift different gear engagement , So, only need to change during Ram is running up and down period , then a little push the lever to next step slot , See simple video about how to change speed .
Ans for Q2:
Under MPG mode or JOG mode , It is called the two mode is “ Manual mode” ,It allows to use lower Ram run, Ram Stop , Ram JOG button function , Usually the 3 buttons is for manually test slotting or to get the first slotting point purpose. Just press Ram Run to continue run the Ram up/down , After Ram run then you Press Ram Stop , The
Ram will stop at top position , If need to stop at bottom position , Just press Ram Run then press Ram Jog button Then ram will stop at near bottom position.
Because there is backward flywheel , So we don’t suggest user to use JOG as touch , touch, touch method to move Ram up/down,User just continues press JOG button then release at near position at what position you want to stop.
See below simple Video.
