Have to love Mach/Sheetcam/Candcnc for allowing upgrades like this. I winged the whole thing, and with the Dotco marker, ended up costing about $325.00 US. Looks better in person, but it's still a start. I have a little fine tuning, but it works pretty well. It was a post I already had running my Plasma (MP3000 DTHC II + Scriber) I did set one of the settings to false, to allow for only one check of the torch at first, and no movement until before the very last one. MIDWEST Scribe Markers have ten preset scribing depths from 1/8 to 1 and are used to scribe mark sheet metal. All the posts seem to trigger that # instead of the #3 like I thought.

Apart from the short time taken to reference it should not make any difference to the scribing or any later plasma cuts.įound out it does not really matter. So the plasma z reference is not needed at all with my setup. I have valves to slow the stroke speed, but they are fully open and it work just fine. It could care less on air pressure on the slide for the most part. Just adjust the stroke adjustment ,and set a stop for travel. If I am doing thicker then 2 inch, then I will have a issue, but there are easy work a rounds for me. I have a Dotco scribe, and it seems like the perfect tool for my marking needs. I can add weight or a adjustable spring if I need more dig. Seem to work perfect with only the weight of the air scribe. The scribe floats on it's own rail after the slide extends. So only offset is just the X and Y for the torch placement. after that, then the torch-to-scribe offset is used to locate the scribe. In order to operate the scribe at the correct height, my controller needs to touch-off the torch to find the correct height depending on the material thickness. I don't know how you can work this without moving the Z axis at all.Īll settings for my scribe's location are relative to the torch's location. It is also used to check the trueness of the flat surface.PK wrote:I have my scribe mounted beside my torch. The scriber point acts as a visual reference against which any variation in the workpiece can be judged. The scriber block may also be used in place of a dial indicator to detect run out (a variation in concentricity) of a workpiece mounted in a four-jaw chuck. Once adjusted, the three arm knob locks the needle in position. The offset distance between the bottom guide and the needle is adjusted using a precision thumbwheel. The upright post can be adjusted to tilt back or forward, effectively moving the scriber point up or down in a controlled fashion coarse adjustments are made by sliding the scriber along its clamping block. The hinge scriber is a sheet vinyl seam scriber designed for accuracy, ease of adjustment, and for good grip and control. The scriber block has pins that can be pushed to protrude through the base these can then be used as limit pins to allow the block to press against the edge of the table, controlling its movement in that plane. The workpiece is held against an angle plate so that it is perpendicular to the surface plate the scriber block is then adjusted to the required height and used to scribe a line parallel with the table, by sliding the block along the table's surface. A scriber block is used to lay out lines at a set height from the base, thus its second name surface height gauge or just surface gauge.
