The magnetic mat we have supplied is not a shim for use every time , it is only needed for making frames or running a selection of frame like dies through at any one time. Simply use the base plate for single dies and increase the pressure switch . The instructions we have supplied are for guidance only , you can increase the pressure switch slightly if you have to and you will get used to the feel of your own machine as they will all differ very slightly.
Also note this is not a miracle machine , it simply will never solve every die cutting problem , but it will solve many and do more for you than most other machines .
If you buy a highly detailed die in all likelihood it will be easier to cut , but you will still have to persevere and work it out . This is a fault of dies with far too much detail . Also there are certain dies on the market that do not emboss , these are much harder to cut out and the same goes for some cheap dies on the market ...you pay for what you get .
